Episode list

A modulated frequency wave cancellation signal isn't something that the Doctor and Romana expect to detect in 1960s London. But then they don't expect to find Professor Lanchester, the man who invented it, lying unconscious. Or MI5 investigating. With the help of MI5 Agent Miller, Lanchester's daughter Jill, and his nephew a pirate radio DJ called Mark, the Doctor, Romana and K-9 investigate. They soon discover that there is more at risk than they imagined, and an alien invasion is about to begin. Can the Doctor identify and defeat the aliens in time? Will Romana manage to find a recombinant transducer before it's too late? And how will K-9 cope with his new job?

The Doctor and Romana land in Budapest, intent on enjoying another holiday, but shortly after landing they find themselves too late to save the life of a man who has seemingly been attacked by a vampire. As they learn that this is the latest in a series of violent attacks, it becomes clear that they have stumbled onto something that needs investigating. Aided by a vampire hunter who is searching for Dracula, they look into the nearby Buda caves, currently being used for storage by the military - and find that the soldiers have problems of their own. Stalked through the tunnels by a monster, and up against an ancient evil, the race is on to escape alive - and foil the dastardly schemes of the maniacal Zoltán Frid.

Whilst travelling in the vortex, the TARDIS is struck by an advanced war machine - a Time Tank. Losing Romana, the Doctor and K9 pursue the Tank to Aoris, a world quite literally at war with itself. Soldiers from the future are attacking the past of their own planet - gathering resources and stealing endangered species. But the past is not without weapons of its own - leaving deadly devices ready to trigger many years ahead after their enemies have been born. Trapped at opposite ends of a temporal war, the Time Lords have two time zones to save. But who is in the right, and who in the wrong? And when history itself is against you, can anybody actually win?

The Doctor, Romana, and K9 have found themselves trapped in a temporal war. On Aoris, the past battles the future - and the future fights back. With both sides of the war now capable of time travel, the conflict is about to enter a deadly stage. As the pieces of history lock into place, there is little the Doctor can do. With more Time Tanks moving into combat, the endgame is approaching. The people of Aoris risk extinction at their own hand. Can even the Doctor save the same planet twice in the same day?

When the TARDIS lands in Brighton the Doctor and Romana have the chance to spend some time at the seaside. But with it being too early for the opening of the Pavilion, they have to look elsewhere for their entertainment - perhaps Madame Tissot's travelling waxworks, recently arrived in town? But they're not the only ones interested in her Exposition. When an unusual thief commits an unusual theft, the time travellers are on the case. What exactly is the sinister secret of Goole's Gallery? Is Tissot's heading for a meltdown? And what does it all have to do with the head of Marie Antoinette?

Altrazar. The temporal Atlantis, a place lost to time. Believed by many to be a myth, it has long been the perfect location for the rich and powerful to hide away their most dangerous secrets. Until now. Because the somewhat crooked, not exactly honest, wheeler-dealer cockney Time Lord known as Drax has found a map that leads to its location. And, at the behest of a manipulative businessman, he's going to use it. When the TARDIS is dragged out of the space-time vortex, its crew aren't best pleased to see the Doctor's old school friend, even less when he pressgangs them into joining a raid on the most secure safe-house in history. However with Romana and K9 held hostage, the Doctor has little choice but to agree. With Drax in tow, he heads for the planet. Which is where the trouble starts.

On a brisk winter's morning in 1850s Yorkshire, Cuthbert, head of the intergalactic business known as "The Conglomerate" prepares to hijack a very special train. In the far future, his assistant, Mr Dorrick is awoken by howling alarms. There is a problem with the Quantum Gateway. In the TARDIS, the Doctor, Romana and K9 detect strange distortions in the Vortex, an energy stream coming from a strange creature called a Laan. The threads of a plan centuries in the making are coming together. But who is behind this plan? And can anyone possibly escape when history is against them?

The TARDIS crew have unknowingly become embroiled in a web of deceit. A trap has been laid across time and they have no possible means of escape. Destiny has ensnared them. The Doctor is finally getting the chance to see the Conglomerate's work at first hand. Romana is working to save the alien Laan once and for all. K9 is returning to Ancient Britain in search of an unusual power source. The Doctor, Romana and K9. Today one of them will die.
