Episode Details

Arc of Infinity

The Doctor's genetic bio-print is stolen from Gallifrey by a traitor, and passed to a mysterious anti-matter alien who then seeks to cross into the ordinary universe by bonding with the Doctor. To prevent this, the High Council sentences the Doctor to death! Can he escape and outwit the mysterious alien?

Snakedance

The evil Mara that possessed Tegan (in Kinda) controls her once again, diverting the TARDIS to the planet Manussa, original home of the Mara before it was banished into the outer darkness centuries ago. There, it steals the Great Crystal and tries to use it to cross back into the physical world! Can the Doctor save Tegan and defeat the Mara once again?

Mawdryn Undead

The TARDIS materialises on a huge spacecraft, concealed above the Earth. The Doctor and his companions are separated - the Doctor uses a transmat device to go down to Earth, while Nyssa and Tegan follow in the TARDIS. Arriving on Earth in 1977, Nyssa and Tegan meet up with the (retired) Brigadier and search for the Doctor. They are horrified when they meet a creature that claims to be the Doctor after an unsuccessful regeneration - locked into a continuous cycle of regenerations! But is it the Doctor?

Terminus

The TARDIS materialises aboard a space ship full of lepers heading towards a promised cure on a space station called Terminus at the centre of the Galaxy. Nyssa contracts the disease and the Doctor sets out to discover the true nature of the cure offered at Terminus...

Enlightenment

The White Guardian warns the Doctor of a terrible peril, and sends the TARDIS to an Edwardian racing yacht. The Doctor is amazed when he realised that the yacht is, in fact, a space yacht and that the race is around the Solar system! The Captain, Straker, and his officers are Eternals - immortal beings with little imagination, racing for the ultimate prize of Enlightenment. The Buccaneer Captain of another ship, Wrack, is a servant of the Black Guardian and must be prevented from winning the race at all costs!

The King's Demons

The Doctor and his companions arrive at a medieval joust and are surprised to greeted warmly by King John, who calls them his demons. But a young Nobleman returns, having just left King John in London - this King must be an imposter! Then the Master makes an appearance and the Doctor's worst fears are confirmed...

Doctor: "Well, fortunately, we are in England."

Doctor: "Yes, well..."

The Five Doctors
