Episode list

Drawn off-course, the TARDIS passes through a CVE into a closed universe - a hugely improbable event with a tragically obvious cause. In order to escape inescapable E-Space, the Doctor, Nyssa, Tegan and Turlough are forced to venture in the wilds of planet Alzarius. But they're not the only unwanted visitors to this strange world. A Starliner has landed, captained by Decider Merrion - but why would Merrion risk rousing the Planet that Slept, and the monsters in its marshes? Mistfall is coming. The Marshmen are coming. But while Nyssa and Turlough find themselves caught in the open, in the hands of fanatics who model themselves on the legendary Outlers, the Doctor and Tegan discover that the supposedly secure Starliner affords them no protection from monsters both within and without.

Still looking for a way out of E-Space, the TARDIS crashes to Isenfel - a realm of snow and ice. Snarling beasts stalk the frozen plains, a feisty princess leads the hunt, and a queen in an ice palace rules over her loyal subjects. But this is no fairytale kingdom, and everyone in Isenfel knows the price of survival. While Nyssa and Tegan uncover deadly secrets hidden in the palace, Turlough flees for his life across the tundra. And as for the Doctor... he only ever wants to change things for the better. But in a world such as Isenfel, such a hope may not even be possible.

A Great Darkness is spreading over E-Space. Entropy increases. In search of a last exit to anywhere, the TARDIS arrives on the power-less planet of Apollyon, where the scientist Pallister guards the only way out - a mysterious portal. But the portal needs power to open, and the only power Pallister can draw on is the energy contained within the molecular bonds of all living tissue... The Doctor, Nyssa, Tegan and Turlough soon learn that neither Pallister nor his ally, the space pirate Captain Branarack, will stop at murder to ensure their escape. But they're not the only menace on Apollyon. The Sandmen are coming - creatures that live on the life force; that live on death. Death is the only way out into N-Space. Death, or sacrifice. But whose death? Whose sacrifice?

Jo Grant is shocked to find most of her colleagues are missing. Then she discovers that the Doctor has inexplicably changed. But there's no time to worry about it, as she and her misplaced Time Lord friend are whisked to the mysterious Delphin Isle on a matter of national security. There, they encounter a disturbingly odd form of local hospitality and learn of a highly classified incident that took place during the Cold War. Why exactly have they been brought here? And what is the truth concerning the bodies in the harbor and the vast project being undertaken beneath a cloak of secrecy?

It's been ten years since the final assault on Telos, the last act of the Great Cyber War. Thanks to the Glittergun, humanity prevailed - and the half-machine Cybermen were utterly obliterated. Out on the furthest fringes of the galaxy, however, they left their mark - in the form of a giant Cyber-head, hundreds of feet high. A monument? A memorial? A tomb? The Doctor, the Cybermen's most indefatigable adversary, sets out to investigate... but he fails to return to his TARDIS. Leaving the Ship, his two companions - brave Highlander Jamie MacCrimmon, and super-intelligent Zoe Heriot - find a stranger in the Doctor's place. A stranger in a coat of many colors, who insists that he's the Doctor - transposed in time and space with one of his former selves... But why here? Why now? Has the universe really seen the last of the Cybermen..?

The TARDIS brings the Doctor, Steven and Vicki to the Italian city of Ravenna in the year 540 - besieged by the army of the celebrated Byzantine general Belisarius. Caught up in the fighting, Steven ends up on a boat bound for Constantinople, the heart of the Roman Empire. Rescuing Steven, however, is the least of the Doctor's problems - because he shouldn't be mixed up in this particular adventure at all. Someone has sabotaged his own personal timeline, putting him in the place of his First incarnation... but who, and why? The truth is about to be revealed - but at what cost to all of the Doctors, and to the whole future history of the planet Earth?

The year is 1987, and Britain is divided. In Bradford, strikers are picketing and clashing with the police. In the City of London, stockbrokers are drinking champagne and politicians are courting the super-rich. The mysterious media mogul Alek Zenos, head of the Zenos Corporation, is offering Britain an economic miracle. His partners wish to invest - and their terms are too good to refuse. While the Doctor investigates Warfleet, a new computer game craze that is sweeping the nation, Mel goes undercover to find out the truth about Zenos's partners. The Daleks have a new paradigm. They intend to conquer the universe using economic power. The power of the free market.

The Doctor and Mel land in what appears to be an orbiting warehouse, a delivery facility with a dangerously erratic computer. Whilst Mel is helping with repairs, the Doctor begins to realize that not everything in the warehouse is as it seems. Why do no goods ever seem to leave the shelves? Why are the staff so obsessed with the stocktake? And who is the mysterious Supervisor? On the planet below, the Doctor discovers that the computer might be the least of their problems - and that they should be more concerned with the spacestation's mold and vermin.

Once it was a mining facility. Then later its corridors rang with screams generated by grotesque military experiments. However when the Doctor and Mel arrive on a hostile alien world after detecting a distress signal, the base they find themselves in is almost deserted. But not for long. Soon the Doctor's old enemies, the Sontarans, have landed, and are searching for the remnants of their previous research team. Before long they uncover evidence of strange occurrences on the planet. Of madness and death. They are warriors bred for war, strong of spirit and unafraid of death. To fear the enemy is an act of betrayal. Nothing holds terror for the Sontarans. Until now.

Bletchley Park. Britain's most secret weapon in the Second World War. Inside draughty huts, the earliest computers clatter day and night, decoding enemy transmissions and revealing intelligence crucial to the country's defense. Leading WREN Mrs. Constance Clarke directs her charges to provide vital assistance to the boffins stationed in the Manor House. But a recent arrival among the code-breakers, the mysterious Dr Smith, has attracted the attention of MI5's spycatchers... Over in mainland Europe, Nazi agents are briefed, covert operations planned, and a German submarine embarks on a very secret mission. As encrypted radio waves criss-cross the planet, unearthly forces stir. And when certain ciphers are cracked, something will emerge to threaten all humanity, regardless of allegiance.

Miasimia Goria was a quiet planet, an ancient world of bucolic tranquility... until the Rani arrived with ideas of her own. She planned to create a race of new gods... gods that she could keep on her leash, but those plans went horribly wrong. Now, she languishes in the high security of Teccaurora Penitentiary, consigned there by her arch enemy and old student colleague, the Doctor. But the Rani, always resourceful, ever calculating, knows things about the Doctor's past that he would rather forget. She wants revenge, even if it takes a hundred years... and then she has other unfinished business. The ruins of Miasimia Goria await.

2029 AD. In the desert of Arizona, billionaire philanthropist Dr Hugo Macht is trying to save the world from climate change. But his great project to "scrub the sky clean" with nanoatomic machines grinds to an unexpected halt when his diggers break into something unexpected: a Viking burial barrow containing eight corpses, a mysterious shield, an even more mysterious inscription... and a yet more mysterious traveler in time and space, known only as the Doctor. And that's not even the strangest part of Dr Macht's day. Soon, it'll begin to snow. Soon, the Doctor and his Girl Friday, Mrs. Constance Clarke, will come face-to-face with an ancient horror in the blizzard. A Frost Giant, in need of a new body. In need of flesh.

YOU are the Doctor, a mysterious traveler in time and space. Will YOU succeed in foiling the ghastly plans of the horrible Porcians, the most inept invaders in all the cosmos? Or will you get yourself killed, over and over again?

A spooky old house. A body in the library. A killer on the loose. The Doctor accepts the challenge laid down by the sinister Mr Norris: to solve a murder mystery that's defeated 1,868 of the greatest intellects in the universe... and counting.

The TARDIS brings the Doctor and Ace to the most opulent casino hotel in the cosmos - a haunt of the rich, the famous and the unutterably corrupt. There's a robbery in progress - but is the Doctor really in on the plan?

Tourist spaceship the Daedalus hangs suspended in space, all but three of its passengers having fallen victim to a bizarre infection. But if the Doctor saves those last survivors, he risks destroying the entire human race.
