The Web of Fear
The Web of Fear was the fifth story of season 5 of Doctor Who. It saw the return of the Great Intelligence and its robotic Yeti, as well as Professor Edward Travers. Perhaps most notably, however, it featured the first appearance of Colonel — later Brigadier — Lethbridge-Stewart, played by Nicholas Courtney. UNIT, however, was not introduced until his next appearance in The Invasion.
Before 2013, all but the first episode of the serial were missing from the BBC archive. In October of that year, the remainder of the episodes (with the exception of episode three), as well as those of The Enemy of the World, were returned, having been located in Nigeria. As of October 2013, the near-full story is available for download on iTunes. The third episode remains missing, with only loose reconstructions and the recorded audio track in the BBC’s possession.
The TARDIS continues in flight with the doors open, while the evil Salamander has been ejected into space and time. Jamie flings himself onto the console and activates the door control, nearly being sucked out himself. The Doctor goes to pilot the ship. Jamie mocks him for not being able to properly control the TARDIS. The Doctor intends to prove him wrong.
In the home of Julius Silverstein, amidst his private collection of artifacts, Anne Travers returns from America to meet with her agitated father, Professor Travers. Travers pleads with Silverstein to let him take (or buy) back the Yeti he sold to him thirty years ago, stating that it is dangerous. Silverstein refuses. The Professor claims to have recently reactivated a control sphere, which has since disappeared. Anne suspects his senility is playing tricks on him. She takes her father away at Silverstein’s urging. As Silverstein closes his home for the night, the control sphere breaks through a window and reconnects with the Yeti. As it metamorphoses into a glowing-eyed monster, Silverstein is attacked; he cowers in terror.
In the TARDIS, Jamie tries to convince the Doctor that a light on the console is flashing; the Doctor dismisses it. The Doctor tells Jamie that the light only flashes when they are landing. Victoria notices the light too, and when the Doctor finally sees it for himself, the machine emits landing sounds. Strangely, the scanner reveals they are suspended in space, and, as they watch, the scanner picture (and the TARDIS itself) is enveloped by a web-like substance.
In an underground fortress, Captain Knight is being interviewed about an apparently fallen comrade, Colonel Pemberton, by Harold Chorley of London Television. As the interview concludes, Professor Travers is ushered in. Knight is badgered by the Professor. He explains that Anne asked for him to be brought in. When Knight leaves, the Professor begins badgering Chorley. Chorley attempts to interview him about the “scientific section” and finding “a solution to the problem,” to which Travers opines that the whole of London, if not the whole of England, might be completely wiped out.
The Doctor has rigged up a device. As the web lessens, he plugs it into the console and throws the switch on the device. The TARDIS emits a screeching sound and lurches, knocking the Doctor and his colleagues to the floor. The Doctor announces he has landed the ship about half a mile away from where they were expected, eluding their captors for the moment. The TARDIS having landed, they emerge in a dark tunnel with bars on the edge. Jamie suspects it’s a prison, while the Doctor speculates it may be the dungeon of a castle. As they explore, they find a trench and a fire extinguisher. They then discover a sign revealing they are in the London Underground station at Covent Garden. They head to the surface. The entrance gate to the station at the top of the stairs is closed. When Jamie attempts to rouse a sleeping man just outside, the man falls, dead and covered with web. The newsstand outside reads, “Londoners Flee! Menace Spreads!” Returning to the platform, Jamie hastily jumps onto the tracks. The Doctor quickly and thankfully ascertains that the current which would have electrocuted Jamie is off. The three walk along the tracks into the tunnel, noticing that trains have not been running for some time. They discover a power cable and are forced to hide as three soldiers (Staff Sergeant Arnold, Corporal Blake and Craftsman Weams) appear, letting out more cable from a large spool. The Doctor asks his friends to follow the soldiers at a distance while he finds where the cables lead.
The soldiers stop for a rest. As Jamie and she pursue them, Victoria is startled by walking into a cobweb and cannot stifle a scream. The soldiers, upon hearing this, ambush and capture Jamie and Victoria.
The Doctor reaches the Charing Cross platform, on which several crates of explosives are connected to the cables. As he investigates, he hears a familiar bleeping sound. He ducks onto the tracks and hides under the platform as a Yeti emerges.
Corporal Lane cannot raise communications with a truck at Holborn. Anne enters with a repaired blast recorder and Knight is only too pleased to give her a hand. Chorley enters, complaining of Professor Travers’ obstructiveness, but is ushered out by Knight.
Meanwhile, the Doctor must sit tight as a second Yeti arrives on the platform. Both Yeti cover the explosives in web, using a strange kind of gun.
As Knight continues to set his cap at Anne Travers, Arnold returns with the cables ready to connect for the demolition job and reports the two captured youngsters. Knight is entirely nonplussed, but Anne pushes to make sure there’s no one else in the tunnel before it’s blown up. Arnold takes Jamie and Victoria into the common room and questions them. Jamie makes a snap decision to deny they were with anyone else. Knight comes down to check, at which point Arnold says that the coast is clear, and Knight rushes off. Jamie asks what all that was about and Arnold tells them. Victoria immediately explains about the Doctor.
However, it is too late — Knight has triggered the bomb.
With the Yeti gone, the Doctor is closely examining the web-covered crates. As the bombs are detonated, the boxes glow and flash from underneath the web. The Doctor is thrown from the platform.
Jamie and Victoria wait in their makeshift prison (the common room at the fortress), Jamie berating himself up for risking the Doctor’s life.
Arnold reports to Knight about the Doctor. Arnold is dispatched to investigate as Weams reports that the blast recorder that Anne repaired isn’t working: it hasn’t recorded a blast. Weams suggests sabotage by the Doctor, and Knight goes to interrogate the youngsters further. As Knight, Anne, and Chorley question Jamie and Victoria, Jamie in turn tries to get someone to tell them where they are and what’s going on. Weams interrupts to report contact is reestablished with Holborn, but it sounds like they’re in trouble. Knight asks if it’s a Yeti and leaves with Weams. Jamie overhears the word “Yeti”, and looks askance at Victoria. Lane reports firing heard at Holborn. They overhear what sounds like a Yeti attack, and the line goes dead. Knight collects some soldiers and goes out to investigate; Chorley elects to stay behind.
Arnold and Corporal Blake discover at Charing Cross the explosives’ shattered crates covered in web. With no sign of the Doctor, they note the distinct lack of any blast damage.
Back at the fortress, Travers is working on a control sphere when Anne tells him of the new arrivals who know so much about the Yeti — even the fact that they are robots, something that has been suppressed from the public. Travers rushes off.
Jamie and Victoria suspect it must have been the Great Intelligence that attempted to capture them in space. Travers bursts in and questions them, but Victoria recognizes the 40-years-older man whom they met in Tibet in 1935. Jamie and Travers soon follow suit. Jamie and Victoria explain the danger that the Doctor is in. Travers takes Jamie to find out any news about the Doctor, while Victoria is left to explain to Anne how all this is possible. They rush upstairs to find Arnold. Arnold tells Jamie and Travers what he knows, and his suspicions about the Doctor. Travers stands up for the Doctor. Jamie goads Arnold into taking him out in search of the Doctor.
Victoria has just about convinced Anne of the veracity of their story when Chorley enters and picks up his typewriter, in its case, to work on a story about the Doctor. Anne regards him with contempt, calling him a “sensation-monger” working for the “gutter press.” Chorley presses Victoria for more information, and tells her that Jamie has gone back into the tunnels.
On the way back from Holborn, Knight and Private Thompson construct a barricade across the tunnel from explosives recovered from the dead ammo detail. Lane and Privates O’Brien and Cocksey perform a rear-guard action but are attacked by Yeti. As they gradually retreat towards the barricade, Cocksey loses his footing and is beaten to death by a Yeti. O’Brien’s rifle jams and he is smothered in web, soon dead. Arnold and Jamie meet Thompson, Knight and Lane. The Yetis use their web guns to cover the explosives. Knight tries to shoot the barricade to blow up the tunnel; the blast is contained by the web, which pulsates and then allows the Yeti to pass through. They are trapped by Yeti from the other end of the tunnel and are held prisoner.
Anne questions Travers on whether she believes the story of the Doctor and his TARDIS before speculating on the curious fact that every time he’s met the Yeti, he’s met the Doctor — eventually stating that he must be embroiled somehow. Before he can refute this assertion, Victoria returns with tea, having overheard the conversation. She quickly excuses herself, after which Professor Travers convinces Anne of the Doctor’s innocence.
Out in the tunnels, Jamie, Knight, Arnold, Lane, and Thompson are under guard by motionless Yeti. Suddenly their guards are called away by a bleeping signal, leaving the humans puzzled, but free.
Blake and Weams discuss their various theories on what the Yeti are. One believes that they are aliens, whilst the other thinks they must be part of some kind of bacterial weapon. They also talk how to stop a Yeti: a bullet directly between the eyes, or a grenade. Their attention is soon drawn to an electronic illuminated map board in the Ops Room, where they see that the web fungus is advancing through the tunnels for the first time in three weeks. They bring Travers, Anne, and Chorley to see, and Chorley again starts to blame the Doctor and his colleagues for this sudden burst. Blake notices that there’s no sign of Victoria in the fortress. She has slipped away into the underground tunnels to find the Doctor and tell him of Anne’s suspicions. Chorley says this proves his belief.
As Jamie, Arnold, Knight, and company return through the tunnels, they hear someone approaching; oddly, the man is singing in Welsh. They ambush the soldier, who presents himself as Evans, the driver of the ammunition truck to Holborn. He reports seeing the web advancing, and a Yeti carrying a glass-like pyramid at King’s Cross tube station moving ahead of the web. Jamie excitedly tells the men that if they destroyed that, it would knock out the Intelligence, and he insists on going there and continuing the search for the Doctor. Evans volunteers to go with him as the rest of the men return to the fortress, but as Jamie thanks Evans, Evans assures him that he’ll escape the first chance he gets. Consulting a map, they decide to move to Tower Hill.
Travers is beating down arguments for evacuation of the base, predominantly led by Chorley, when Knight and his party arrive at the fortress and are brought up to date. Knight shuts down any talk of escape. All of the Circle Line has been consumed by the web now, with the exception of Monument.
As they arrive at Monument, Evans stops Jamie. They hear a dull noise echoing through the tunnel. They look up to see the web approaching. They double back only to find more of the web cutting of their escape. As they await their death, they hear a screeching noise and are forced to cover their ears.
Episode 3 (Lost)
Out of the web advances a Yeti carrying a pyramid. Jamie gets Evans to shoot the pyramid, which makes the pyramid explode and the Yeti become immobile, but the web continues to advance. They make a dash for an archway, and escape.
Meanwhile, Victoria finds the Doctor in the tunnels, accompanied by a Colonel Lethbridge-Stewart. She tells the Colonel about the fortress at Goodge Street, and, at his prompting, tells the Doctor about the presence of Travers, and his apparent suspicions about the Doctor. The Colonel escorts them to the fortress.
With the Circle Line completely cut off and the fortress hemmed in, Knight is informed of the return of the Doctor and Victoria, and the arrival of the Colonel. Knight goes down to talk to his new guests.
In the common room, the Doctor calms Victoria and says that the Colonel hasn’t harmed him in any way. When Knight enters the Colonel presents his papers of authorization and tells Knight that he is Colonel Pemberton’s replacement. The Colonel was part of the attacked ammunition party at Holborn, and Knight mentions to him that driver Evans survived also, still not quite certain if his new C.O. is the real thing. Travers bursts in and, after a happy reunion, takes the Doctor and Victoria to the lab. The Colonel questions who is actually in charge of the base.
Once away from army ears, the Doctor tries to confirm that suspicions are not focused on him, as Victoria had suggested. Travers rubbishes this, and Anne owns up to it being an idle thought of her own. They muse about the Great Intelligence and its reasons for trapping the TARDIS, while Victoria worries about Jamie.
Meanwhile, Jamie and Evans arrive at St Paul’s tube station.
At the same time, Chorley is arguing with Arnold about trying to escape, saying his reports to the outside world are important. Arnold dismisses any thought of getting through the web but says there is a door that leads directly up to the surface. Chorley goes to investigate.
In the lab, Travers tells the Doctor about reactivating a control sphere, which must have allowed the Great Intelligence to zone back in on the spheres and the Yeti. Knight collects them all for a briefing to be given in the common room. Victoria asks if there is any news on Jamie; Knight is sorry that there isn’t.
Evans plans to escape at the next station, Chancery Lane, hoping to find his lorry and get out of town. Jamie argues with him as they walk through the tunnels, but Evans separates from him.
At the briefing, the Colonel discuss the arrival of a mysterious mist in London: anyone who goes inside the mist never comes out again. The mist completely interferes with radio and other communications. The Colonel also explains how the mist led to the fungus and then, two days later, the Yeti. The Doctor and Travers note the new appearance of the Yeti compared to their adventures in Tibet. Anne reports that she and her father believe they could jam transmissions from the Intelligence, but need more equipment. Chorley bursts in, clearly agitated that he was not told about this briefing, and argues that an exit to the surface, mentioned by Arnold, could allow a helicopter to airlift them out. The Colonel dismisses him, and his attempts to pull rank as a member of the press are met with scorn. Chorley leaves to question Weams in the Ops Room about tall buildings in this area, including the Post Office Tower. Weams leads him to a map to show him the position of the Tower, but sees the further development of the fungus and leaves to tell the Colonel about another advance of the Web.
Jamie sees Evans approaching, hides, and surprises him. Evans pretends that he had a moment of conscience, but then admits the gates at Chancery Lane were locked. They make their way back to the fortress.
The Colonel decides to give Chorley a liaison job, coordinating things (and tucked safely out of the way in the common room), while the rest get to some real work. The Doctor suggests buying some time by blowing up the tunnel at Goodge Street and sealing themselves in. He plans to set of the explosives on a baggage trolley as it rolls down the tracks, therefore avoiding any Yeti attempts to cocoon it. The Doctor and Travers set to work on a detonator.
Meanwhile, someone in the fortress unlocks the main door, leaving the base open and vulnerable.
In the lab, Victoria recognizes the model Yeti that Anne shows her (as she saw in Tibet), but as the Doctor comes in, Anne realizes that one of the models is missing. The Doctor is clearly concerned by this.
Someone changes the base on the stolen model Yeti, then places it on the floor. It begins to beep. In response to the signal, a Yeti in a nearby tunnel comes to life and moves off.
Travers has constructed the mechanism for the detonator. Victoria points out that Jamie will be trapped outside the fortress if their plan succeeds.
The main door slowly opens and a Yeti walks in. The Yeti moves towards the model Yeti and breaks the lock to the explosives store.
The Doctor is running through the plan with the Colonel when Arnold comes in and reports the opening of the main door. Another soldier reports finding a broken padlock and a model of a Yeti outside the explosives store. They rush off to investigate. Weams picks up the model Yeti.
The Doctor and his army friends listen at the door and hear nothing. They open it to see a bright luminous web rendering their explosives futile.
Anne and Travers console Victoria, who is still worried about Jamie. Travers speculates that Jamie may be far safer than any of them are.
Arnold reports to the Colonel that the fortress is still Yeti-free. The Colonel decides to take a group of men to Holborn to see if any explosives are still usable; both the Doctor and the Colonel suspect this is a waste of time, but know they must check. The Colonel will leave the Doctor four men. The Doctor announces that someone inside the base must be in league with the Yeti, citing the evidence of this latest precision attack.
Victoria foolishly tells Chorley about how she’s worried the explosion may cut them off from the TARDIS and Jamie. Chorley, not knowing about the tunnel which would trap him in here, finds the temptation of the TARDIS too much. As the Doctor arrives, Chorley leaves surreptitiously. The Doctor soon discovers her gaffe, and also discovers they are locked in the common room.
Chorley meets Jamie and Evans, safely arrived at the fortress, and they tell him the Colonel’s party has gone to Holborn. Chorley leaves the base. Jamie and Evans hear the banging from the Common Room. Jamie releases the Doctor and Victoria, and he and the Doctor leave in pursuit of Chorley.
As Travers and Anne work in the lab, a scream is heard. Travers soon finds Weams dead in the Ops Room, a Yeti model lying beside him. As Travers picks it up, a Yeti roars from behind him and attacks.
Travers tries to run but is attacked. Anne appears, and just as she sees her father on the ground, she too is struck down. The Yeti drag away the Professor.
The Doctor, Jamie, Victoria, and Evans are en route to Convent Garden, trying to intercept Chorley, who the Doctor suspects will attempt to use the TARDIS to escape from the Underground.
The Colonel and Arnold meet up with Knight, who reports running into the web a mere 100 yards from Holborn. Arnold notes that it was as if the Intelligence knew what they were up to. Knight suggests attempting another route, via Piccadilly, and the Colonel leads the party there.
The Doctor and his party run into more of the web before reaching Covent Garden, but he cannot be sure if Chorley made it to the TARDIS before the web arrived. He collects a sample of the web in Evans’ tobacco tin (casually discarding the tobacco inside, much to Evans’ irritation). The web pulsates and releases a shrill noise but the Doctor manages to get a sample.
Arnold and Blake are investigating a tunnel, and just after Blake’s return to the main party, the Doctor and party find Arnold. Arnold then reports back to the Colonel as the rest return to the fortress to experiment on the web.
The Doctor and company discover the main door hanging off its hinges, and soon discover web-covered furniture, equipment — and bodies. They discover Anne in the lab and rouse her from unconsciousness. She is soon hysterical as she tells of her father’s fate, and Jamie and Victoria help her to the common room. The Doctor speculates on why Travers wasn’t killed — he believes they must have some use for him. Upon their return The Doctor tells the Colonel and Knight about what has happened. Evans is drafted by Arnold to help with the bodies, and on his exit greets the Colonel, whose memory is refreshed about the lorry driver to Holborn. The Doctor and the Colonel are summoned by Blake to the Ops Room, where more stations are being overtaken by the web as it advances towards Goodge Street. The Colonel muses about the Doctor’s suggestion of a traitor in their midst. Knight and the Colonel suspect Travers having some sort of involvement, whilst the Doctor suspects Chorley. The Doctor tries to explain what exactly the Great Intelligence is, that he and his friends are time-travelers, and that their police-box-shaped craft is at Covent Garden. Knight responds with derision but the Colonel accepts the Doctor’s story. He asks the Doctor if the TARDIS could help them escape. The Doctor said it could but he needs to finish the work that Travers started. Jamie enters to take the Doctor to Anne, who is asking for him. Despite Knight’s strong doubts, the Colonel decides to try to rescue the Doctor’s craft. Knight wonders if this is a trap set up by the Doctor.
The Doctor explains that the only way to find Travers is to find the central control source. The Doctor wonders why the Yetis chose to attack now and Anne tells the Doctor that Travers was about to connect a controlling unit to the Sphere. The Doctor demands that Anne shows him the sphere.
Anne shows the Doctor a contraption she has made, that controls the sphere but won’t override the Intelligence’s commands. The Doctor says they can fix that. Evans enters, giving the Doctor the model Yeti found by Weams’ body, as per Arnold’s instructions. The Doctor is horrified to be given it, and Evans denies any wrongdoing, as Anne realizes all the other models are gone. Evans indignantly hands over his tobacco tin filled with web, for fear of being accused of wrong doing again.
The Colonel’s plan gets underway: he and his party will attempt to reach Covent Garden station on the ground, while Arnold, Lane, and Evans will attempt to meet them underground via a baggage trolley, using it to carry the TARDIS back to the fortress; Knight is ordered to remain on duty at the fortress.
Meanwhile, the Doctor attempts to observe the web in the tin, but the tin is empty; the Doctor’s suspicion of Evans grows. Arnold is also suspicious of Evans and warns him not to try and escape from his party. The Doctor informs Knight of Evans’ potential involvement. The Doctor wants Knight to accompany them to the surface to obtain vital equipment needed to upgrade the controlling unit that is to be attached to the control sphere. He is initially unsure but a bit of gentle persuasion from Anne sees him yield.
Arnold’s party come up against a web barrier near Covent Garden, and Lane puts himself forward, when Evans refuses to volunteer, to attempt to get through the web on the trolley with Arnold. The two men don respirator masks. Evans pays out a rope attached to the wagon as they go deeper into the web, but the two men scream as they enter, the web pulsating with light. Evans fearfully pulls at the rope, and the trolley emerges, with Lane’s web-covered body sprawled out on it. Arnold is gone.
On street-level, the Colonel and his men arrive at Covent Garden, but find Yeti waiting for them. After ducking into a builder’s yard the Yeti find another way in, and the men open fire to no effect. However, their hand grenades prove very effective, felling a great number of the robots. The Yeti also smash down the main gate and force the men across the yard, killing some soldiers as they advance. Three men trapped behind a trader’s cart are pinned down and killed by web guns. The bazooka is also employed to good use and another soldier is killed before the remaining troops retreat into a warehouse.
Knight stands outside a nearby electrical shop, M. Thompson & Son Electricians, listening to the distant gun fire while the Doctor collects supplies. Knight goes in to hurry the Doctor when two Yeti appear in the doorway, felling Knight. The Doctor finds a model Yeti in Knight’s pocket.
One back in the base The Doctor shows the model to Jamie who puzzles over who must have planted it. Evans, again, protests his innocence. The Doctor speculates where the other models might be.
In the warehouse, Corporal Blake and the colonel have run out of ammo. They climb above some boxes. Blake is grabbed by a Yeti and is killed. The Colonel, the only survivor, runs back to the fortress.
The Doctor dismantles the model Yeti as he and Anne start work with their new equipment. Victoria and Jamie are discussing who the traitor might be (Jamie suspects Chorley), when the Colonel staggers in and tells them of the fate of his men. Evans reports the fact that his party were all wiped out too. Suddenly the Doctor shushes the room when he registers a faint bleeping sound. He realizes the Colonel has the last model Yeti planted on him by the traitor. Two Yeti burst into the room, accompanied by Professor Travers.
The Great Intelligence speaks through the possessed Travers, saying the trap laid for the Doctor was so that it could possess him and his unsurpassed mind. It has created a machine that will drain all past knowledge from the Doctor’s mind, leaving his body unharmed and his mind wiped clean, but he must submit willingly. If the Doctor gives himself over to the Great Intelligence all deaths will stop — both in the tunnels and in London. To ensure his submission, Travers takes Victoria hostage and leaves, giving the Doctor twenty minutes to decide. A Yeti remains outside the lab door, so Jamie cannot go after Victoria despite his anger, but the Doctor persuades everyone that the Intelligence cannot harm her or Travers if it is to obtain the Doctor’s cooperation. Evans asks the Colonel why they don’t just give the Doctor over to the Intelligence so they can all go home.
Travers and the Yeti take Victoria through the tunnels, Victoria subtly dropping her necklace on the track.
As the Doctor, the Colonel, Jamie and Anne discuss their options, Jamie and Evans come to loggerheads about the Welshman’s insistence they hand the Doctor over. The Doctor sides with Evans and says he will hand himself over if he can’t think of a plan. Evans discovers that a Yeti is no longer guarding them. The Colonel takes Evans and Jamie to search the base, while Anne and the Doctor work again on the control sphere and box.
Jamie wants to go up top to overtake the Yeti and ambush them. The Colonel is skeptical but complies when Jamie intends on going himself. Evans is to stay and guard the Doctor and Anne.
The Doctor has made a breakthrough regarding the control box and turns his attention to the sphere.
The Colonel and Jamie open the door to the surface and find the web pulsating beyond. The Colonel holds it off while Jamie opens a fire exit. The Colonel rushes away allowing the web to creep in.
Meanwhile, the Doctor reactivates a control sphere just as Jamie returns to them, telling them of their situation. The Colonel and Jamie are dubious about the merits of the Doctor and Anne’s work, but are persuaded to leave them alone as they return to work on the control box.
Evans confronts the two men, claiming they must be working for the Intelligence: it did say it had another pair of hands working for it. Jamie dismisses his accusation, claiming it must have been Chorley. The Colonel and Jamie try their luck in the tunnel, ignoring Evans’ show of ill discipline
At Piccadilly Circus Station, the Intelligence speaks through the air, orders Travers to release Victoria, and then releases him from possession. It promises the pair that it will reveal itself to them soon. As Travers recovers his wits, they try to escape from the Yeti on the platform, only to run into another.
The Doctor and Anne successfully use the box to control the sphere, but only at short range; they set to work on reprogramming the sphere itself. The next objective is to set it to work verbally. Anne reminds him he only has twelve minutes left.
The Colonel and Jamie make their way through the tunnel. Jamie is now hostile to the Colonel, suspecting him to be affiliated with the Great Intelligence. Jamie discovers Victoria’s necklace on the tracks in the tunnel and continues after her.
At Piccadilly, now guarded by two Yeti, Staff Sgt Arnold appears and, avoiding sight of the Yeti, tells Travers and Victoria he will try to get back to base.
Evans is startled by the appearance of a control sphere at his feet, but the Doctor stops him before he tries to shoot it. It is now under the Doctor’s control. The Doctor and Anne leave for the tunnels, heading towards Warren Street to try to find a Yeti to put their control sphere in and control. Evans refuses to join them.
The Colonel and Jamie meet up with a shaken Arnold. He cannot remember anything after entering the web. Despite Jamie’s protests, he and the Colonel take him back to the base.
At a signal, the Yeti shepherd Travers and Victoria and move them along the platform.
In the Ops Room, Evans is hiding behind the electronically illuminated map board of the underground system, having heard something approaching. The Colonel, Jamie, and Arnold enter. Evans is shocked and speechless at seeing Arnold again. When Evans explains where the Doctor and Anne have gone, the Colonel and Jamie go out after them.
The Doctor and Anne encounter a wall of fungus, and as they examine it, they discover a Yeti is behind. The Doctor hastily gets out the control box and — at dangerously close range — the Yeti freezes. They quickly replace its control sphere with theirs, and soon the Yeti is obeying the Doctor’s commands.
Evans has dressed Arnold’s head-wound, but as Evans returns the medical gear to the lab, he yells out in fear to Arnold; the wall of the laboratory is bulging, and it soon gives way as the mist, the precursor to the web, spills into the room.
Arnold and Evans abandon the base as it is engulfed by the web. Arnold wants to warn the others, but Evans deserts him, fearful of the web. Arnold angrily shouts after him.
The Doctor and Anne, in the tunnel with their controlled Yeti, decide not to tell anyone else about their success. The Doctor orders the Yeti to wait for them to leave, then resume acting for the Intelligence until he says otherwise. The Yeti obeys, and they leave.
Jamie and the Colonel meet up with the Doctor and Anne, who are surprised to hear that Travers and Victoria are at Piccadilly, and that Arnold (who is still alive) told them so. The Doctor and Anne deny that their technology worked and that they must return to HQ as the Doctor’s twenty minutes are almost up.
The Doctor’s Yeti reactivates after ninety seconds, and is soon joined by two more Yeti who move off together into the tunnels.
Arnold is soon found by the party, and he tells the Colonel that the H.Q. has been swamped by web. No sooner are they all together than they are surrounded by the three Yetis.
In another tunnel Evans successfully hides from a Yeti but two more find and capture him, despite his best attempts at trying to talk his way out of it.
The Doctor and his colleagues are being led through the tunnels by two Yeti. Arnold asks the Colonel to create a distraction. The Colonel pretends to hurt his ankle and Arnold escapes from the Yeti.
Travers and Victoria are led into the Booking Hall at Piccadilly Station, where they discover a large glass pyramid; inside the pyramid is a smaller upside down pyramid which forms a seat. Travers explains that this is the machine the Intelligence has created to drain the Doctor’s mind. Victoria spots a figure lurking in the shadows, but it runs off before they can see who it is. As they discuss the Doctor’s future, the Intelligence speaks to them through a speaker on the wall, insisting on their cooperation and non-interference. Travers wrings his hands at having brought this onto the world thanks to his curiosity.
As the main party is guarded on the Piccadilly platform, the Doctor explains to Jamie about the controlled Yeti. He gives Jamie a microphone to use to call the controlled Yeti to him — hopefully it will be the right one.
A frightened Harold Chorley finds Arnold and tells him his stories of the surface, the Yeti, fear, and the strange machine at Piccadilly station, including the Yeti and their two prisoners, for it was he that Victoria saw lurking in the shadows. A suspicious Arnold wonders how he could possibly have survived all this time, and tells Chorley to come with him.
Anne suggests the Doctor use his control box in order to escape but the Doctor tells Anne there’s no point in trying to escape now as he must meet the Intelligence face to face. The Colonel says that the Yetis have not noticed Jamie’s disappearance and asks the Doctor if he’s going to give himself up, for the good of everyone, including his friends. Before he answers, Evans is brought in. The Colonel tries to reprimand Evans for abandonment but Evans says he was trying to save Travers and Victoria. Two Yeti start to move the Doctor away towards the Booking Hall, and he insists that his friends don’t struggle or resist. As they leave, Jamie pops his head out from a large metal bin.
In a passageway a Yeti approaches the Doctor carrying some kind of headset, and as it begins to lower it onto his head, he switches on his control box and the two Yeti become motionless. He takes the headset from the Yeti, makes some rapid adjustments to the circuits, and replaces it in the Yeti’s grasp. They place the device on the Doctor’s head.
Anne is reunited with her father and the inner sanctum of the Great Intelligence. A worried Victoria asks about the Doctor and Jamie.
Back on the platform, Jamie is speaking into the microphone, attempting to bring the controlled Yeti to him. A Yeti appears, but though Jamie is unable to make it follow further commands, it does not harm him, but moves off back into the tunnels. As Jamie turns to leave, a Yeti is behind him.
Most of the group are now gathered in the Booking Hall, as the Doctor is ushered in, wearing the headset. As the Doctor again warns his friends away from interference, the Intelligence is heard thanking him for his cooperation. The Colonel yells out at the Intelligence to show itself, but it says that will happen soon enough. Chorley emerges, and the entire assembly gasps, thinking him to be the Great Intelligence. He desperately protests his innocence, exclaiming the identity of the real “traitor,” Staff Sergeant Arnold.
The possessed Arnold appears now wearing a metallic headset, stating that it, the Great Intelligence, has manifested itself in his lifeless body. The Great Intelligence informs the Doctor’s friends that it has no intention of letting them leave unscathed. Jamie is brought in by a Yeti, and all the survivors are present. Arnold orders Jamie to stand by the Doctor when, suddenly, a Yeti grabs Jamie by the throat. The Doctor protests and refuses further cooperation until Jamie is released, and Arnold orders the Yeti to release him with the threat that if the Doctor doesn’t comply Jamie will be killed.
The Doctor is instructed to submit to the Intelligence and he does so willingly and sits in the pyramid. The Great Intelligence connects a lead inside the pyramid to the Doctor’s headset. As the Great Intelligence announces the beginning of the transfer, Jamie yells out for the controlled Yeti to attack. First it attacks its comrades — in the ensuing confusion the other Yeti attack each other and the Colonel, who is knocked to the floor. The controlled Yeti then proceeds to throttle Arnold at the order of Jamie. As the transfer continues, the Doctor vociferously resists Jamie’s attempts to rescue him. Anne and Prof. Travers assist Jamie as he pulls the Doctor, who is yelling and pleading to leave him in the pyramid, and soon the Doctor is free. Jamie pulls the wiring out of the pyramid, which explodes.
The Yeti are disabled and Arnold is killed. As the smoke clears and congratulations are exchanged, the Doctor is furious and despondent at Jamie and the others. He had altered the circuits so that instead of the Intelligence draining his mind, he would have drained the Intelligence. Instead of them putting an end to its evil, it has simply been cut off from contact in space. They find Arnold’s blackened husk of a body.
