The Zygon Invasion

Written by Peter Harness
Directed by Daniel Nettheim

“Operation Double is a covert operation, outside of normal UNIT strictures, to resettle and rehouse an alien race, in secrecy, on planet Earth.”

A long time ago, the Doctor made a deal in the Tower Of London. 20 million Zygons walk among us, in human form, living undetected in peace and harmony. But cracks are showing in this delicate peace. Humans and Zygons are disappearing. In city apartment blocks, lifts are going missing, and far below the streets of Britain, alien pods are growing in secret caverns. Unit’s scientific advisor, Osgood, sends a desperate message to the Doctor – but since Osgood is long dead, how is that even possible?


Once upon a time… There were three Doctors….. and two Osgoods….

The Zygon Invasion opens with a view of the Doctors in Day of the Doctor, with a flash to Osgood being d51-600x312copied by a Zygon. We then see a video that has been made by both the Zygon Osgood and the human Osgood together. They never say which is the human and which is the Zygon. They state that they are the living embodiment of the treaty made on that day. They explain that UNIT is helping the Zygons to assimilate into Earth and there are now twenty million Zygons living on the planet in human form. Between them is a box. This box is never to be opened except in the event that one of them dies. They explain the Nightmare Scenario, which is what happens when the treaty breaks down and people begin to die with no one knowing who is Zygon and who is human.

After the video cuts out, Osgood is running through a building during what looks like a military battle. She hides under a desk and takes out her phone. On the screen, she is seen to be sending a message to The Doctor. Just then, footsteps are heard coming into the room. It is a Zygon. The Zygon walks around the desk and kidnaps her. She drops her phone onto the ground. The message has been sent.

Meanwhile, The Doctor is in the TARDIS, playing “Amazing Grace” on his guitar. The console alarm goes off and the display shows an incoming message from Osgood with two words: “Nightmare Scenario.”196d79

The Doctor is seen at a playground, calling Clara. He tells her that the ceasefire is breaking and he has gone deep cover. He approaches two children and talks to them about the ceasefire breaking and tells then that they need to work together to stop the splinter factions from starting a war. They tell him that they have it under control and to leave it to them, just as a Zygon device is deployed while smoke rises from it and the two Zygon leaders are taken. The Doctor heads to UNIT headquarters, still trying to call Clara.

Meanwhile, Clara arrives at her apartment and sees that The Doctor has tried to call her 127 times. She calls him back and sees a young boy crying on the stairs. He tells her that he can’t find his parents. She looks in his apartment and the parents sneak up behind her. She tells them that their son is having trouble finding them and the father drags him, screaming, into the apartment. She asks if he is okay while the parents stare at her. After this, Clara is seen calmly walking out of the apartment and she calls The Doctor. “Did you just call yourself Doctor Disco?”

Clara meets The Doctor at UNIT headquarters and they watch another video that has been sent by the Zygon splinter group. In it, Osgood explains that the Zygons want to be able to live on the earth as they Doctor-Who-907-15-600x337really are and they want to control the world. “Truth or Consequences.” Later, Kate, Clara, and The Doctor discuss what to do next, and what that phrase could mean. Clara explains that Truth or Consequences is a town in the United States and she knows this because she memorizes a lot of trivia. The Doctor explains that Clara will remain in London with UNIT and he will go to the US to check out the town and try to find Osgood.

The Doctor arrives in Truth or Consequences to stop an airstrike on the town. He convinces the forces to let him go into the village and talk to the Zygons to get Osgood back. Meanwhile, Kate has made her way into town and enters a police station. There is an officer there who tells her all about how the Zygons were discovered and killed everyone in the town. During this time, The Doctor and UNIT forces go into a village to try and get Osgood. The Zygons take the form of the loved ones of the soldiers to trick them into entering the building and killing them. The Doctor and the UNIT leader break into the building to find the soldiers dead. He hears Osgood screaming from below and finds a hidden stairwell into the cellar. He frees Osgood from her chains and a Zygon stops them. Just as they are ready to be taken, a bomb goes off above them, burying the Zygon in debris. Meanwhile, Kate is back at the police station, trying to discover what she can about the Zygon splinter group when the police officer reveals that she is a Zygon.

Back on the plane, The Doctor speaks with Osgood about the breakdown of the ceasefire and what it could mean. He asks her to tell him if she is the Zygon or the human. She tells him that is a question she will never answer because she and her “sister” were the living embodiment of the ceasefire and that she will not break that, even with the other Osgood dead. He tells her that he knows she is the human 0x600because Zygons need the original to remain alive to maintain a psychic link and keep form. She explains that new technology has allowed for the Zygons to maintain form, even when the original is dead.

In London, Clara brings UNIT into some caverns underneath her apartment building. They enter a large cavern with pods all over the walls and ceiling. She orders the UNIT soldiers to destroy them because they are hundreds of Zygons waiting to be hatched. When she pulls away the cover of one of the pods, her own face is revealed. She acts surprised to see it and orders the soldiers to destroy them again. Another UNIT woman explains that the Zygons don’t grow copies. They are born in normal form and have the ability to shift into the forms of other beings and that these are the original humans. Realization dawns on her face as she looks at Clara in the pod. The Zygon Clara looks at her while dozens of the UNIT soldiers revert to Zygon form and kill the rest of them. She picks up her phone and makes a call. Kate answers. “UNIT is neutralized in The United States.” Zygon Clara responds that UNIT is also neutralized in The UK, mostly.

Zygon Clara enters the armory and takes the pieces to a rocket launcher assembly. She calls The Doctor to inform him that the real Clara is dead. She lifts the rocket launcher and shoots it at the Presidential plane……
