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 lands on the seveneenth century Cornish coast, and its crew stumble upon a plot by the local Squire to receive and offload contraband goods. The Doctor meets the churchwarden, whose last words to him concern the whereabouts of hidden treasure. When pirate captain Samuel Pike learns of this, he kidnaps the Doctor and demands to be given the cryptic clue.

The TARDIS materialises at the Roof of the World, Central Asia, in 1289. There they meet Marco Polo and his fellow travellers on their mammoth journey across the Pamir Plateau and through the Gobi desert to Peking. Unfortunately for the Doctor, his Ship proves to be of immense interest to Polo, who sets his mind on presenting it to the mighty Kublai Khan on arrival at his court.

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.

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.

Patrick Troughton witnesses 'the final end' of the Daleks in this exclusive recording of a classic 'lost' BBC television adventure, with linking narration by Frazer Hines.

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 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?

The Cybermen make their first ever appearance whilst William Hartnell's Doctor nears the end of his first incarnation, in this classic soundtrack adventure with linking narration by Anneke Wills. The year is 1986, and at the South Pole the crew of the Snowcap Base have detected a new planet on their radar. The arrival of the Doctor, Ben, and Polly at the Base coincides with another landing, that of a spaceship whose humanoid passengers have used cybernetics to replace their limbs and vital organs.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

It’s 1984, and life has changed beyond recognition. Airstrip One, formerly known as Great Britain, is a place where Big Brother is always watching, and nobody can hide. Except, perhaps, for Winston Smith. Whilst working at the Ministry of Truth, rewriting history, he secretly dreams of freedom. And in a world where love and sex are forbidden, where it’s hard to distinguish between friend and foe, he meets Julia and O’Brien and vows to rebel.

Inheriting your uncle's supervillain business is more complicated than you might think. Particularly when you discover who's running the place. Charlie's life is going nowhere fast. A divorced substitute teacher living with his cat in a house his siblings want to sell, all he wants is to open a pub downtown, if only the bank will approve his loan. Then his long-lost uncle Jake dies and leaves his supervillain business (complete with island volcano lair) to Charlie. But becoming a supervillain isn't all giant laser death rays and lava pits.

Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he's sure he'll be the first person to die there. After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he’s alive - and even if he could get word out, his supplies would be gone long before a rescue could arrive. But Mark isn't ready to give up yet.

Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you're not a rich tourist or an eccentric billionaire. So smuggling in the occasional harmless bit of contraband barely counts, right? Not when you've got debts to pay and your job as a porter barely covers the rent. Everything changes when Jazz sees the chance to commit the perfect crime, with a reward too lucrative to turn down.
