The Zygon Invasion was the seventh episode of the ninth series of Doctor Who produced by BBC Wales.

This story is the first to be a sequel to a previous story, in this case the 50th Anniversary Special The Day of the Doctor, having a sequence dedicated to show the beginning of the plot point of this story.

Synopsis

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. To top it all off, UNIT's scientific advisor, Osgood, sends a desperate message to the Doctor - but since Osgood is long dead, how is that even possible?

The Doctor, Clara and UNIT must scatter across the world in a desperate bid to set her free. But in a world of shape-shifting aliens, who can you trust? And can the world be saved before it's too late?

Zygons

  • After the Human-Zygon peace treaty, seen in TV: The Day of the Doctor, 20 million Zygons were relocated around the United Kingdom. It quickly became clear that these Zygons had seized control of the UK and had slowly spread across the entire globe.
  • The Zygons have training camps.
  • The Zygons use pods to contain humans.
  • Bonnie uses an A.A.P.L.S. B-Type Transponder weapon to fire at Boat One.
  • Places the Zygons have invaded include the Mexico border, North Asia, West Africa and Australia.

Story notes

  • The Radio Times programme listing was accompanied by a small colour shot of Osgood and the Doctor, with the accompanying caption "Doctor Who / 8.15 p.m. Osgood is snatched by aliens, prompting a round-the-world rescue mission".
  • Given that the "Clara" in most of this episode is a Zygon duplicate, this is the second consecutive episode in which the real Clara is only on screen for a brief portion.
