Sheridan Moorkurk has just been elected president of Earth...And what's more, she's starting to hear voices. Meanwhile, the Doctor and Romana encounter a mass of aliens heading to Earth - aliens who have already made the mistake of upsetting the infamous Cuthbert, all-powerful CEO of The Conglomerate, by destroying one of his space platforms. Will the Doctor and Romana be able to avert interspecies war that will destroy all life on Earth?

The Doctor and Romana are enjoying a leisurely lifestyle as the Lord and Lady of a London townhouse. But trouble never stays away from them for long, and before they know it a chance discovery of alien technology leads them deep into the heart of the English countryside, where a malign presence lurks. As the Doctor dodges deadly butlers and ferocious gamekeepers, Romana is faced with a malevolent aunt and an even deadlier peril - marriage. Directed by Ken Bentley.

The Doctor and Romana find themselves in the Proxima System, where enigmatic Conglomerate CEO Cuthbert has been conducting his infamous 'experiment'.

On their mission to explore the Mariana Trench at the very bottom of the ocean, the deepest and most inhospitable place on Earth, the crew of the deep sea vehicle Erebus make an unusual and startling discovery. A battered blue police box. As the Doctor, Romana and K9 join them on their journey, the submariners soon discover that the TARDIS is not the only unusual find lurking on the sea floor.

Britain. The height of the Roman occupation. The Doctor has brought Leela to ancient Norfolk to learn about her ancestors...but has no idea how much of an education she is going to get.

As Leela begins to be swayed by the warrior queen's words, the Doctor has to make a decision: save his friend...or save history itself?

The Doctor, Romana and newly elected President Sheridan Moorkurk take on the all-consuming powers of business tycoon Cuthbert and his vast Conglomerate.

But when his revenge looks like it's leading to interspecies war, the Doctor knows the stakes couldn't be higher. The Laan are on the move. Is it too late to prevent the destruction of all life on Earth?

Professor Litefoot and Henry Gordon Jago are accustomed to the murky fog of Victorian London and the palatable pints of half and half at the Red Tavern. They are not used to travelling through time and space with their old friend the Doctor. And now they find themselves whisked off to the planet Venus in the distant future, at a time when warrior women rule from a floating city in the clouds. There’s a mystery here, one that the Grand Empress Vulpina intends to keep secret. Even if it means destroying these visitors from the long-dead planet Earth....

To continue Leela’s education, the Doctor promises to take her to the famous Morovanian Museum. But the Tardis lands instead in a quiet English village, where they meet the enigmatic collector Harcourt and his family. When people start to die, reality doesn’t appear quite what it was. There’s something sinister going on within the walls of Harcourt’s manor, and the stakes are higher than they can imagine.

Cuthbert's plan for the Proxima System is reaching its final phase. The Doctor and Romana have been separated. The Doctor is aiding the Proximan fight-back. Romana and K9 are prisoners of the Daleks. And as the countdown to the opening of the Quantum Gateway begins, the Daleks reveal their true intentions.

The first time the fearsome Kraals attempted to take over the Earth, with the help of their android agents, things didn't go quite according to plan - thanks to the time-travelling alien Doctor and his allies at UNIT. This time Marshal Grinmal and his belligerent cohorts are ready for them. This time they'll make no mistakes. This time Chief Scientist Tyngworg has not just one plan but a backup plan and a backup backup plan worked out.

The legend dates back to Roman times, at least: a great White Worm, as wide as a man, slithers out of the rocks of the Dark Peak Gap to take animals, sometimes even children, for its food. When the Doctor and Leela arrive in the wilds of Derbyshire only to get caught up in the hunt for a missing girl, they soon discover that the legend of the Worm is very much alive - even now, in 1979. Worse still, it seems that the Doctor isn't the only renegade Time Lord on the trail of this deadly and mysterious Worm....

The travellers are about to discover the secret of the lost colony...and it may cost Jago's life.

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.
