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'.

Three feature-length Doctor Who adventures. In 'Doctor Who and the Silurians' (1970), Jon Pertwee stars as the third Doctor, who is called to an atomic research station in Derbyshire to investigate a series of mysterious events. His questions uncover a vicious ring of in-house saboteurs and something a bit more slimy. In 'The Sea Devils' (1972), after visiting their old enemy the Master (Roger Delgado) in his remote island prison, the Doctor (Pertwee) and Jo learn of several recent accidents at sea, all of which have been accompanied by reported sightings of strange monsters. The Doctor discovers that the creatures responsible are the Sea Devils, acquatic cousins of the Silurians who are out to reclaim the planet Earth from mankind. In 'Warriors of the Deep' (1983), The Doctor (Peter Davison), Tegan and Turlough arrive at an underwater base on an Earth in the future on the brink of Atomic War. Helping to trigger this war are the planet's original inhabitants, the Silurians and the Sea Devils, aided by their killer pantomime horse, the Myrka.

Another adventure for everyone's favourite Time Lord. The Doctor (Jon Pertwee) and Jo (Katy Manning) travel to Stangmoor prison to investigate a machine which can remove evil from the minds of criminals. However, the man behind the scheme - Professor Kellerman - is in fact the Doctor's arch-nemesis, the Master (Roger Delgado), and is planning to disrupt a United Nations peace conference. Inside the Master's machine is an alien parasite which can make people see their greatest fears, and is growing stronger all the time. Can the Doctor stop both the Master and the unearthly parasite?

Another adventure for everyone's favourite Time Lord. The arrival on Earth of a UFO brings with it the Axons - golden-skinned aliens who offer the gift of Axonite to mankind. The Doctor (Jon Pertwee) is suspicious, especially when he discovers that his old enemy the Master (Roger Delgado) is on board the Axon craft.

Jon Pertwee stars as the time travelling Doctor, who once more finds the planet under threat. Trying to avert a war which will bring Earth under the domination of the Daleks and their ferocious slaves (the Ogrons), the Doctor fights one of the biggest challenges he has faced so far.
