Everyone's favourite time traveller returns to do battle with his greatest foes. Years after his peremptory departure from Totters Lane (see the first ever story, 'Doctor Who: An Unearthly Child'), the Doctor (Sylvester McCoy) returns to 1963 London to discover that the military have been called in to do battle with an alien invasion force at Coal Hill School. The aliens turn out to be none other than the Daleks, whose Emperor wants to obtain a Gallifreyan stellar manipulator - known as the Hand of Omega- which was left in the Doctor's care. However, a group of renegade Daleks are also after the Hand, in league with a fascistic human group. Can the Doctor defeat both Dalek armies and prevent the Hand of Omega being misused?

Sylvester McCoy plays the Doctor and Bonnie Langford his assistant, Mel, as they journey to a hi-tech housing block. Once a paradise residence, now a run down and almost deserted nightmare city, a war has developed over the years of its downfall. The Doctor is soon on the case when sinister happenings begin to occur.

Two classic Doctor Who adventures, one from the 1970s and one from the 1980s, both featuring those sinister humanoids the Cybermen. In 'Revenge of the Cybermen' (1975), the Doctor (Tom Baker), Sarah Jane (Elisabeth Sladen) and Harry (Ian Marter) return to the space station Nerva (from 'The Ark in Space') to recover the TARDIS. They discover the crew decimated by a strange plague, to which Sarah falls prey. The Doctor realises that the plague is part of a plot by the Cybermen to destroy Voga, the planet of gold - gold being the only thing which is lethal to them. At the same time the Vogans are planning to destroy the Cybermen with their Skystriker rocket. The three-part adventure 'Silver Nemesis' (1988) was made to celebrate Dr Who's 25th anniversary. A statue, blasted into space 350 years ago, crashes into Earth in the core of a meteor. The Doctor (Baker) and his assistant Ace (Sophie Aldred) must fight two armies from different time periods, a regiment from 1988 and a battallion of soldiers from 2688, whilst guarding the statue from the clutches of the Cybermen.

The first story from the final season of Sylvester McCoy's tenure as the Doctor. The Doctor and Ace arrive on Earth in the late 1990s where they become involved in a battle between King Arthur and Morgaine. However, these are not the heroes of Britain's past but warriors from another dimension - and they recognise the Doctor as the wizard Merlin. As usual it is down to the Doctor and Ace to save the planet, but this time they find some help in the guise of the Doctor's old UNIT ally, Brigadier Lethbridge-Stewart.
