Another adventure for everyone's favourite Time Lord. The Doctor (Tom Baker), Sarah and Harry land on space station Nerva, where the chosen few of the human race are in suspended animation, awaiting the call to revive. However, an insectoid alien life form known as the Wirrn has infiltrated the Ark and cut through the humans' alarm clock. The Wirrn now intend to use the sleepers as the hosts for their hatchings and claim the Earth as their own.

The last adventure to star Jon Pertwee. To save the Universe, the Doctor must travel to the planet Metebelis Three, where he discovers an invasion plan of Earth by the Metebelis Spiders, under the leadership of the Great One. To save the planet the Doctor must absorb a lethal dose of radiation, triggering his third regeneration...

Two classic Doctor Who adventures set on the planet of Peladon, starring Jon Pertwee as the Third Doctor, with Katy Manning as his companion in the first story and Elisabeth Sladen in the second. In the four-parter 'The Curse of Peladon' (1972), the Doctor (Pertwee) finally seems to have escaped his exile to Earth when he manages to transport Jo (Manning) in the Tardis to the planet Peladon. The pair are mistaken for Earth delegates at a conference to decide whether Peladon should join the Galactic Federation, and discover that someone is attempting to use the legendary royal beast of Aggador to trigger off a war. In the six-parter 'The Monster of Peladon' (1974), the Tardis arrives on the Planet of Peladon half a century after the Doctor's first visit. The planet has now become of great tactical importance because of its focal position between warring factions. The Doctor and Sarah (Elisabeth Sladen) have to act as peacekeepers between rival ambassadors and they must also find the truth behind 'the spirit'.

The Doctor (Tom Baker) and Sarah (Elisabeth Sladen) arrive on storm ridden planet Karn, where mad scientist Dr Solon (Philip Madoc) is creating a hybrid monster body for the brain of renegade Time Lord Morbius (voice of Michael Spice). Also on the planet are the Sisterhood of the Flame, who believe that the Doctor has been sent by the Time Lords to steal their Elixir of life. The Doctor must convince the Sisters of his good intentions and prevent Solon from returning Morbius to life.

More adventures with everyone's favourite time-traveller. In 'Full Circle', it soon becomes clear that all is not well when the Tardis scanner shows the Doctor (Tom Baker), Romana (Lalla Ward) and K9 an image of Gallifrey, only for them to discover an expanse of marshland when they venture outside the ship. The Doctor realizes that they have somehow travelled through a charged Vacuum Emboitment into E-Space where he meets the local Alzarians - themselves preparing to retreat to their damaged spacecraft, the Starliner, in an attempt to escape the lethal Mistfall. In 'State of Decay', when the Doctor, Romana and K9, still trapped in E-Space, land on a medieval planet, they do not realize that Adric has stowed away on the Tardis with them. They are soon in need of his help when they discover that the local society is ruled over by three vampire lords - Zargo (William Lindsay), Camilla (Rachel Davies), and Aukon (Emrys James). Finally, in 'Warrior's Gate', the Doctor may finally be on the verge of escaping E-Space when the Tardis is hijacked by Biroc (David Weston), a time-sensitive Tharil on the run from Captain Rorvik (Clifford Rose) and his crew of privateers. However, when K9 is damaged by the Time Winds, it becomes clear that he will not be able to make the return journey.

All four classic Doctor Who stories featuring the alien species, the Sontarans, who first appeared in the 1973 story, 'The Time Warrior'. The Sontarans are a self -cloning race who live in a militaristic society in the 'southern spiral arm of the galaxy'. Humanoid in appearance, with a squat build and distinctive dome-shaped heads, they are far stronger than mere humans and possess an unquenchable thirst for war. The other stories in this set are 'The Invasion of Time' (1977), 'The Two Doctors' (1984) and 'The Sontaran Experiment' (1975).

The Doctor (Tom Baker) and Sarah Jane return for a visit to Earth, only to discover that a wave of evil Mandragora energy has hitched a ride on the TARDIS and is now being used to plunge mankind back into the dark age. They have to thwart not only the murderous count, but also prevent the mad monk Heironymous and the Cult of Demnos from unleashing the Mandragora Helix on mankind.

The entire 16th season of the long-running cult classic. Tom Baker, the popular fourth Doctor, is joined by the beautiful Romana (Mary Tamm) in this 26-episode intergalactic treasure hunt for the all-powerful Key to Time. Includes six storylines: 'The Ribos Operation', 'The Pirate Planet', 'The Stones of Blood', 'The Androids of Tara', 'The Power of Kroll' and 'The Armageddon Factor'.

Three digitally remastered Doctor Who stories from the 1960s, '70s and '80s. In the three-part 'The Seeds of Death' (1969), the Doctor (Patrick Troughton), Jamie (Frazer Hines) and Zoe (Wendy Padbury) travel to a moon relay station to find out why T-Mat, a form of instant travel, has broken down. There they discover a race of Ice Warriors, planning to use T-Mat to carry seed pods to earth which will produce a deadly fungus to suck the air dry of oxygen. The Doctor has to foil the Ice Warriors' plan, avoiding the deadly pods along the way. In the four-part 'Carnival of Monsters' (1972), the Doctor (Jon Pertwee) and Jo (Katy Manning) find themselves arrested as stowaways after the TARDIS makes an unplanned arrival on the S.S. Bernice, en route to India in 1926. However, the ship is in fact trapped in a miniscope - the mechanical peepshow of intergalactic showman Vorg (Leslie Dwyer). When the Scope is impounded by officials on the planet Inter-Minor, many of the creatures contained within get loose, including the monstrous Drashigs. In the four-part 'Resurrection of the Daleks' (1983), the Daleks are once again seeking their creator, Davros (Terry Molloy), to discover a cure for the Movellan virus. Mercenaries free Davros from his prison ship, but the Kaled scientist has other ideas, and soon a Dalek civil war is underway. On 20th-century Earth the Doctor (Peter Davison), Tegan (Janet Fielding) and Turlough (Mark Strickson) are caught up between the rival factions and the Earth rebels, but they are already part of a larger plan to destroy Gallifrey.

Three digitally remastered Doctor Who episodes from the 1970s, '80s and '90s. In 'The Talons of Weng-Chiang' (1977), the Doctor (Tom Baker) and Leela (Louise Jamison) arrive in Victorian London to find that galactic war criminal Magnus Greel has created giant rats in the sewers and is sucking the life essence from young girls to sustain him in his search for his time cabinet. Aided by Professor Litefoot and music hall proprietor Henry Jago, the Doctor must stop Greel (masquerading as the Chinese god Weng Chiang) and his servants Li H'sen Chang and killer doll Mr Sin. 'The Caves of Androzani' (1984) represents the final outing for the fifth incarnation of everyone's favourite Time Lord. The Doctor (Peter Davison) and Peri (Nicola Bryant) become embroiled in an underground war of gun running and drug smuggling shortly after landing on the planet Androzani Minor. Apprehended by the military, they are rescued from execution by the brilliant but horribly disfigured criminal, Sharaz Jek, whose infatuation with Peri looks set to be cut short when he discovers that both she and the Doctor have contracted the deadly disease Spectrox Toxaemia. The only possible cure is the milk of the queen bat, which dwells in the caves currently being roamed by the killer Magma Creature... In 'Doctor Who: The Movie' (1996), the Doctor (Sylvester McCoy) crashlands the TARDIS on Earth in end-of-century San Francisco while en route to return the Master's remains to their home planet of Gallifrey. Gunned down by a street gang, the Doctor is rushed to hospital, where exploratory surgery by Doctor Grace Holloway (Daphne Ashbrook) triggers a regeneration. The Master has meanwhile taken over the body of a paramedic and infiltrated the Doctor's TARDIS, which he plans to use in his latest scheme to take over the Doctor's new body and destroy the world. Filmed as the pilot for a revived 'Doctor Who' series - tailored to the American market - which subsequently failed to materialise, this feature-length adventure introduces Paul McGann as the renegade Time Lord.
