Another adventure for everyone's favourite Time Lord. When the TARDIS makes an unscheduled landing on a mysterious spacecraft heading towards planet Earth, the Doctor (Peter Davison) and his cohorts are surprised to find that the crew members are drawn from a variety of ancient Earth cultures. Their leader, however, is a frog-like alien known as Monarch (Stratford Johns), and the more the Doctor finds out about his plans for the future of Earth, the less he likes them.

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.

The Fourth Doctor departs, the Fifth arrives and the Master returns in these three classic 1980s adventures!

When the Doctor (Peter Davison) tries to take Tegan (Janet Fielding) back to Heathrow Airport, the Tardis arrives in the 17th century instead of the 20th century. The time-travellers discover that a space capsule has landed nearby and its alien occupants intend to wipe out life on Earth by releasing rats infected with a great plague.

Two episodes of the classic sci-fi series featuring the Fifth Doctor, Peter Davison, and the shape-changing android Kamelion. In 'The King's Demons' (1983), the renegade Time Lord forces Kamelion (Gerald Flood) to pose as King John in 13th century England. 'Planet of Fire' (1983) sees the Doctor (Davison) and Turlough (Mark Strickson) arriving in Lanzarote on Earth to investigate the transmission of an unusual signal that turns out to be emanating from a mysterious alien artefact.

All 12 episodes of the Black Guardian trilogy from the twentieth season of the long-running sci-fi series. On discovering public schoolboy Turlough lost aboard an apparently abandoned cruiser in space, the Doctor (Peter Davison) transports to Earth in 1983, only to meet up with his old friend friend and UNIT colleague, Brigadier Lethbridge-Stewart, who has apparently lost all memory of him. Back in 1977, Tegan and Nyssa meet the younger Brigadier and a disfigured alien they believe could be a regenerating Doctor. However, it turns out that this is all in fact part of a plot to destroy the Doctor by the Black Guardian, who has made a deal with Turlough to grant him transportation away from Earth if he kills the Doctor. Episodes are: 'Mawdryn Undead (Parts 1-4)', 'Terminus (Parts 1-4)' and 'Enlightenment (Parts 1-4)'.
