Season Twelve - 1974/1975
After his latest regeneration the Doctor is left to recover in the sick bay. While he is resting a huge robot enters a secret laboratory and steals the plans, and components, for a disintegrator gun.
Sarah Jane Smith finds that the robot was invented by Professor Kettlewell whilst he was working for Think Tank. On leaving the group he had ordered the robot destroyed. Sarah and the Doctor visit Think Tank, and find that the director, Miss Winters, had not destroyed the robot, and had in fact reprogrammed it.
The Think Tank group used the robot, and the disintergrator gun, to obtain nuclear missile codes from a government official. Members of the group hide away in a nuclear missile bunker, and plan to use the missile codes to start a nuclear war, destroying all life on the planet. They could then emerge as the new rulers of the world.
The Doctor manages to get into the bunker and halt the countdown, and the missiles are later disarmed. Professor Kettlewell had also developed a metal virus, and this is used by the Doctor and Harry to destroy Kettlewell's robot.
