All six episodes, including two that are animated due to their being missing from the BBC archives, of the second Doctor's classic 1967 adventure. In 'The Ice Warriors', the Doctor (Patrick Troughton), Jamie (Frazer Hines) and Victoria (Deborah Watling) arrive on Earth in the year 3000 AD - in the middle of the second Ice Age. At the Brittanicus Base, a team of scientists struggle to control the elements with a machine known as the Ioniser. When a body is found perfectly preserved in the ice barrier which surrounds the base, it is thawed out. The creature proves to be an Ice Warrior - one of an agressive reptilian race from Mars, intent on awakening its fellows and conquering the Earth.

An early adventure for the sixth incarnation of everyone's favourite time traveller. The Doctor (Colin Baker) and Peri arrive in 1985 London shortly after avoiding a collision with Halley's comet, lured by a galactic distress call. They discover that the city's sewers are populated by Cybermen, intent on changing history by preventing the destruction of their home planet, Mondas (see 'Doctor Who: The Tenth Planet'). It transpires that the distress call which attracted the Doctor's attention was sent by none other than former Dalek ally Commander Lytton, but just whose side is he on this time?
