(4 episodes): Four Hundred Dawns - Trap Of Steel - Air Lock - The Exploding Planet

When the TARDIS lands on an arid planet, it seems as though the whole place is desolate and lifeless. But then the Doctor, Steven and Vicki discover two crashed spaceships: one contains the Drahvins, a race of stunning beauty, the other contains the hideous Rills. However, as the team soon find out, appearances can be deceptive. It emerges that the beauty of the Drahvins hides a colony of mindless clones who are controlled by the cruel, powerful matriarch Maaga, whereas the ugly Rills are friendly and intelligent explorers. The Rills tell the Doctor that the dried-up planet is about to die. Back in the control room of the TARDIS, he discovers they are right, but things are worse than they thought. There is only one day of life left, one day to escape. With the Drahvins' ship damaged beyond repair, can the Rills get off the planet before the evil Maaga hijacks their craft in her own effort to escape?

(4 episodes): Temple of Secrets - Small Prophet, Quick Return - Death Of A Spy - Horse of Destruction

The Doctor has adopted many guises in his time, but to be hailed as the great god Zeus is a bit of a shock. Yet this is exactly what happens when the TARDIS lands on the plains of Asia Minor, not far from the city of Troy. Taken to the Greek camp by Achilles, the Doctor is introduced to Agamemnon and Odysseus and forced to admit his less-than-godlike status. He is then given just two days to come up with a strategy for defeating the Trojans. Meanwhile, Steven and Vicki have been taken prisoner by the other side. The Trojans are convinced that Vicki is a spy and to prove her loyalty she must concoct a plan to defeat the Greeks! Like the Doctor, she has just two days to do it. Luckily for the Doctor, a certain someone has already devised a scheme for beating the Trojans. Even if the wooden horse was invented for a piece of fiction written in the eighth century, it still works. As the opposing forces come face to face in a climactic battle, there are dangers aplenty for both Steven and Vicki. By the time the TARDIS moves away again, it will have both lost and gained a crew member...

The Doctor seems well-acquainted with the mysterious mandarin's penchant for deadly distractions, but now with companions Steven and Dodo in tow, the stakes are even higher. Failure to triumph in a series of games will result in them being trapped for eternity in a strange realm where innocuous-seeming nursery characters reveal lethal intent. Steven and Dodo's desperation to regain the TARDIS increases with every round of blind man's buff and musical chairs that they play. In each game they face dangerous opponents and deadly allies: the clowns Joey and Clara, the King and Queen of Hearts, a mischievous schoolboy and a legion of silent, walking dolls... The Doctor, rendered invisible and challenged to complete the fiendishly difficult Trilogic Game, can only watch his friends' plight from afar. Who will be the first to make a false move in this battle of wits, and will the TARDIS ever escape the Toymaker's snare?

The Clanton brothers have ridden in to settle a grudge with Doc Holliday, the notorious gambler, drinker, and dentist. In the Wild West, tempers are short, guns are swift, and a moment's hesitation on the draw can mean death...

(4 episodes)

When the TARDIS materialises on an alien planet, the Doctor insists that he and his companions have arrived in the far future. Steven and Dodo think otherwise, however, after they encounter a band of cave-dwelling primitives who are terrified of strangers. The travellers soon discover that the planet's population is divided, and that the professed idyll of the Elders, who inhabit a technologically advanced city, seems oddly dependent upon the unsophisticated Savages. Whilst the Elders' leader, Jano, welcomes the Doctor into their society, Dodo stumbles upon a dark secret at the heart of the community. The truth behind the Elders' great knowledge is eventually revealed, and the Doctor sees it as his duty to end a terrible case of exploitation. Yet Jano has plans of his own for the Doctor... With the Doctor's faithful companion Steven discovering that events on this planet will irrevocably shape his destiny, The Savages marks the final appearance in the programme of Peter Purves, who also provides the linking narration for this release.
