The astronauts came back wrong. Space radiation, or something wearing their faces?
Astronauts rescued from a mission to mars are kidnapped when they arrive back on earth. They seem to have been irradiated, and can now kill people merely by touching them. But the Doctor discovers the astronauts have been replaced with Alien ambassadors who are being forced to behave in a hostile manner. With The Doctor traveling to the alien mother ship, and Liz kidnapped, The Brigadier is left wondering who to trust.
Practical Effects
Glorious retro-futurist spacesuits and alien costumes that aged beautifully weird.
Writing
Cold War paranoia meets first contact — surprisingly political for 1970.
