The Doctor and Romana find themselves in the Proxima System, where enigmatic Conglomerate CEO Cuthbert has been conducting his infamous 'experiment'. An experiment which might accidentally rip the universe apart. Meanwhile, living conditions on Proxima Major have become harsh and hostile. Climate change has turned the landscape into a freezing wasteland and an alien power has condemned much of the population to life inside internment camps.

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.

It's 1812, and the Doctor, Steven and Dodo get ready to spend their winter in a Russian village. The French are on their way, but that's not the only invasion the travellers will have to deal with. Written by: Marc Platt. Directed by: Nigel Fairs.

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.

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.

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 Leela find themselves in the middle of London at the time of a new energy crisis. The GlobeSphere Corporation seems to have all the answers - but several thousand protestors beg to differ. What is the connection between the National Gallery and a base on the moon? Has radical thinker Damien Stephens simply sold out, or does he have a more sinister agenda?

They call him The Pugilist. It is the dawn of a new century and a vigilante is on the loose. The scourge of the criminal underclass. The saviour of the virtuous and the protector of the weak. The police are baffled, the public enamoured...but Professor George Litefoot and Henry Gordon Jago are on the case. Or at least they will be when they've finished their beer. What is the source of The Pugilist's spectacular supernatural powers? Is he alone in his noble quest?

Big Finish's first Fourth Doctor adventure. A great jumping-on point.... After saying their good-byes to Professor Litefoot and Henry Gordon Jago, the Doctor and Leela respond to an alien distress call beamed direct from Victorian England. It is the beginning of a journey that will take them to the newly built Space Dock Nerva...where a long overdue homecoming is expected. A homecoming that could bring about the end of the human race. Written and directed by Nicholas Briggs.

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....

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?

Unfinished business. A frightened girl is stalked in a land of eternal night. A hunter longs for recognition and power.

Originally broadcast on BBC Radio 7.... 'The crashed ship. The one Tom Cardwell saw all those years ago. And you borrowed its technology, didn't you? Maybe even found a Dalek or two in the wreckage. Dead but intact. And you began to turn human beings into creatures like them.'
