Patrick Troughton stars as the Doctor in this serial from the fifth series of the popular sci-fi show. When the TARDIS escapes from peril in space into the London Underground network, the Doctor and his companions, Jamie McCrimmon (Frazer Hines) and Victoria Waterfield (Deborah Watling), discover that danger lurks in the British capital, too. A robot yeti, unleashed by the carelessness of Professor Travers (Jack Watling), is wreaking havoc. Can the Doctor find a way to contain the creature and the alien forces lurking in the background?

Two classic Doctor Who adventures set on the planet of Peladon, starring Jon Pertwee as the Third Doctor, with Katy Manning as his companion in the first story and Elisabeth Sladen in the second. In the four-parter 'The Curse of Peladon' (1972), the Doctor (Pertwee) finally seems to have escaped his exile to Earth when he manages to transport Jo (Manning) in the Tardis to the planet Peladon. The pair are mistaken for Earth delegates at a conference to decide whether Peladon should join the Galactic Federation, and discover that someone is attempting to use the legendary royal beast of Aggador to trigger off a war. In the six-parter 'The Monster of Peladon' (1974), the Tardis arrives on the Planet of Peladon half a century after the Doctor's first visit. The planet has now become of great tactical importance because of its focal position between warring factions. The Doctor and Sarah (Elisabeth Sladen) have to act as peacekeepers between rival ambassadors and they must also find the truth behind 'the spirit'.
