The travellers arrive in the dangerous domain of the Toymaker, where their failure to win at a series of games could result in them becoming his playthings for eternity. Apparently innocuous nursery characters reveal deadly intent, and for companions Steven and Dodo the stakes are raised with every game of blind man's buff and musical chairs. The Doctor, meanwhile, is rendered invisible and given the challenge of completing the fiendishly difficult Trilogic game.

The TARDIS lands in Paris in 1572 at the time of the massacre of the French Protestants at the hands of the Catholic Queen Mother, Catherine de Medici. Worryingly for the TARDIS crew, it appears that the hated Catholic dignitary the Abbot of Amboise is a dead ringer for the Doctor himself.

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 first Doctor becomes the second in this exclusive recording of Doctor Who's orginal regeneration story, starring Patrick Troughton with linking narration by Anneke Wills.

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.

Materialising in a forest, the Doctor and friends find themselves 12 kilometres from Paris. It is the 18th century, and France is the scene of an ongoing battle between royalists and revolutionaries. Following a blaze at a farmhouse, Ian, Barbara, and Susan are separated from the Doctor and arrested as traitors. Ian receives information about James Stirling, an English spy vital to the revolution. No one seems to know where Stirling is, and locating him becomes Ian's priority.

History must take its course...' The TARDIS materialises in the middle of a holy war between King Richard the Lionheart and the Saracen leader, Saladin, in 12th Century Palestine. As the Doctor, Vicki, Ian and Barbara explore their surroundings, they are suddenly caught up in a Saracen ambush - and Barbara is kidnapped. For the time travellers, intrigue and espionage ensue as they once again become involved in living history.

Patrick Troughton plays the second Doctor in this four-episode adventure from 1967, set on Earth's moon and featuring a return appearance by the emotionless Cybermen. The year is 2070, and the Earth's weather is controlled by a device called the Gravitron which is under threat from a plague epidemic and the Cybermen.

The TARDIS arrives on an extinct volcanic island, beneath which lies a fantastic subterranean world inhabited by the primitive Atlanteans. The Doctor and his companions move from the frying pan to fire when they are rescued, from death at the jaws of hungry sharks, by the mad Professor Zaroff, whose plans involve nothing less than the destruction of the whole world.

In it the time travellers arrive in Scotland in the aftermath of the battle of Culloden, meeting up with a band of fleeing Highlanders. Polly and the daughter of the group's Laird, whose battle injuries are being treated by the Doctor, go off to fetch water and return to find that the others have been captured by Redcoat troops. Can the Doctor save the day?
