The Doctor

The Doctor, Liz and UNIT are at Space Control, investigating the mystery surrounding Mars Probe 7, which began its return journey from Mars seven months ago, but has made no contact with Earth in that time. The centre is headed by Professor Ralph Cornish, who is overseeing the Recovery 7 rescue mission, which has now also run into difficulties. Recovery 7 returns to Earth, but after landing, the astronauts are kidnapped. Liz notices that the Geiger counter is at a maximum, which indicated radiation levels that would have killed any humans aboard. It transpires that the ship's occupants were not the human crew after all, but instead are a trio of radiation dependant alien ambassadors, who have swapped places with them. The Doctor makes a solo flight in Recovery 7, and docks with Mars Probe 7, which is still orbiting in space. A huge alien spaceship intercepts the Probe, and the Doctor is taken on board, where he finds the real astronauts unharmed. The alien captain threatens to destroy the Earth unless the three ambassadors are released. The Doctor is allowed to return to Earth, and discovers that the kidnapping of the ambassadors is part of a scheme devised by General Carrington, a xenophobic ex-astronaut. The General plans to discredit the aliens, and to convince the world's authorities to wage war against them. The Doctor and UNIT stop his plans, and arrange for the safe exchange of the astronauts.

Notes:
*Featuring the Third Doctor, Liz, the Brigadier and UNIT

*Part 4 was transmitted 30 minutes late due to 'Grandstand' overrunning

*Only part 1 exists in full colour, while parts 2-7 survive as black and white film recordings and poor-quality domestic colour recordings made from a US transmission in the 1970s. For the story's 2002 VHS release, the usable colour information from the domestic recordings was combined with the black and white picture from the film prints to create a high-quality colour picture; more than half of the story's running time was presented in colour on this release, including all of episodes 1 and 5; the remaining footage was deemed unsuitable for colour restoration. Allegedly, episodes 2-7 exist in color on tape recorded in the US

*Working titles: 'Carriers of Death' and 'Invaders From Mars'
