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?

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.

The TARDIS materialises in an English quarry where Sarah is involved in a rock fall. When she is rescued, she is clutching a stone hand, which takes control of her and forces her to take it into the core of a nuclear reactor. The Doctor (Tom Baker) arrives too late to stop the hand from regenerating into an alien lifeform known as Eldrad, who demands to be returned to her home planet of Kastria. The Doctor obliges, but all is not as it seems with Eldrad. This was Sarh Jane Smith's last adventure with the Doctor, although she later returned in 'K-9 and Company', 'The Five Doctors' and 'Downtime'.

Another adventure for everyone's favourite Time Lord. UNIT is called to a sleepy mining town in South Wales to investigate the mysterious death of a miner in an inactive pit. The Wholeweal environmental community believe that a local chemical company has something to do with the death, and when the Doctor heads a mission down the mines he discovers thousands of maggots surrounded by poisonous slime. Further investigation at the chemical works reveals the owner to be under the malign influence of a sentient computer, BOSS.

Double bill of classic 'Doctor Who' television serials. 'Invasion of the Dinosaurs' (1975) is the last storyline to feature Jon Pertwee as the Doctor. When a group of scientists who want to return the Earth to a time before technology use dinosaurs to try and force people to flee the cities, the Doctor and Sarah Jane Smith (Elisabeth Sladen) set out to stop them. In 'The Android Invasion' (1975) the Doctor (now played by Tom Baker) and Sarah Jane believe that they are back on Earth when the TARDIS lands near what seems to be a peaceful English village. But why is the local pub deserted? And who are the spacesuit-wearing figures with guns for fingers? The intrepid pair set out to discover the truth.

The Master (Roger Delgado) has stolen some top secret information giving details of one of the most destructive weapons in the known universe, and it is up to the Doctor (Jon Pertwee) to get that information back. The Doctor's quest takes him to the planet Uxarieus, where he becomes caught up in a dispute between the human settlers and the Interplanetary Mining Corporation. Meanwhile, the Master remains at large, and with murderous robots and rampant lizards to contend with, the Doctor's search for the all-important doomsday machine become evermore difficult.

The Doctor (Tom Baker) and the newly-regenerated Romana land on a strangely familiar planet and investigate the drilling that is going on there. The Daleks are searching for their creator, Davros (last seen in 'Genesis of the Daleks'), in the hope that he can assist them in their war with the Movellans. The Doctor has to reach the evil Kaled scientist before the Daleks, but just who can he trust?

The Doctor (Patrick Troughton), Jamie and Zoe land on the planet of the Gonds, the brightest of whom are periodically selected to serve the unseen Krotons, and never seen again. When Zoe and the Doctor are selected too, the battle is on to destroy the crystalline aliens.

Another adventure for the sixth incarnation of the intrepid time traveller. The Doctor (Colin Baker) and Peri arrive on the planet Necros to pay their last respects to deceased agronomist Arthur Stengos. They discover that his final resting place - Tranquil Repose - is in fact a front for a Dalek farm run by the Great Healer, who turns out to be none other than the Doctor's old foe, Davros.
