The Doctor and Mel visit Paradise Towers, a residential complex that promises a peaceful life to its residents. However, the establishment is far from what its name suggests: A conflict persists among the Kangs, humanesque multicolour beings who gather in opposing gangs based on which colour of the rainbow they bear; killer cleaning robots prowl the halls, and a secret in the complex's basement poses the greatest threat of all.

A race of giant Gastropods has taken over the planet Jaconda. Their leader, Mestor, now intends to cause an enormous explosion in order to spread his people's eggs throughout the galaxy, and he kidnaps juvenile twin geniuses from Earth to work out the necessary mathematical equations. Space fighters led by Lieutenant Hugo Lang are dispatched to get the twins back, but they come under attack and Lang is the sole survivor when his ship crashes on the asteroid Titan III. A newly regenerated Doctor and Peri become involved and help Jaconda's elderly former ruler Professor Edgeworth, who is really a Time Lord named Azmael, to defeat Mestor and free the planet's bird-like indigenous people from the gastropods' reign of terror. Azmael, however, sacrifices his life in the process.

Produced for American Public Television, this documentary on the long-running Doctor Who television series features interviews with actors and actresses who played the traveling companions of the Time Lord hero and with three actors, Jon Pertwee, Peter Davison, and Colin Baker, who portrayed the title character, as well as footage of a U.S. fan convention where Tom Baker, appeared and answered questions. The fan backlash against the 1985-6 hiatus for the series and the finding of some previously lost Jon Pertwee era episodes are addressed, and this documentary closes with some on-the-street interviews with British viewers, who tell who their favorite Doctor is.

Omega, an ancient Time Lord made of pure anti-matter, once defeated by the Doctor, is plotting to cross over into this dimension by bonding with the Doctor. Meanwhile, the disappearance of a man in Amsterdam piques the curiosity of his cousin, Tegan, who previously left the Doctor at Heathrow Airport and now finds herself at Omega's mercy. Fearing total destruction from the collision of matter and antimatter, the Time Lords recall the Doctor to Gallifrey to undertake the only viable solution: executing him!
