Mission to the Unknown is the only episode not to feature the Doctor, as it is a scene setter for the Dalek Masterplan. Per-episode titles ceased after the Gunfighters, with the story now carrying the name and each episode being numbered. Vicki elects to stay behind with the fleeing Trojans at the end of The Myth Makers. In The War Machines, DoDo leaves and Polly and Ben join as companions. Steven elects to stay behind as the leader of the Savages at the end of The Savages.

Episode Details

Two races, the Rills and the female-dominated Drahvins, have both landed on a planet that is about to spin out of orbit. The Doctor uncovers a plot by the Drahvins to steal the space ship belonging to the Rills in order to escape destruction...

Mission to the Unknown

Space Agent Mark Cory lands on a dangerous jungle planet known as Kemble and discovers that the Daleks are there in force and involved in a sinister plan.

The Myth Makers

The Doctor and his companions materialize outside the walls of Troy and are captured by the Greeks. Mistaken as a Greek elder and then falling under suspicion, the Doctor is given two days to bring down the walls of Troy. He invents a large wooden horse and arranges for it to be left outside the city walls while the Greeks withdraw...

The Dalek Masterplan

The Guardian of the Solar System, Mavic Chen is planning to use the Daleks as a tool in a plan for global domination. The Doctor and his friends stumble across a message left by Mark Cory and try to warn the authorities, but find themselves hunted as traitors. After deceiving the Daleks, the Doctor, Steven and Sara Kingdom travel through time to ensure their escape. Unfortunately, the Daleks have a time machine and give chase leading to a confrontation in ancient Egypt.

The Massacre

Paris 1572: the Catholic Queen Mother Catherine de Medici is planning to kill all the Protestants in France. The TARDIS crew rescue a servant girl, Anne, who has overheard the plot being hatched. Together, they try to warn the Protestants, but their warnings fall on deaf ears...

The Ark

The Doctor and his companions arrive on a large Ark in space and attempt to assist the residents. Unfortunately, they fall seriously ill with a common cold; a virus to which they've never been exposed before. The Doctor manages to find a cure and they leave, only to materialize in the same place but centuries later. The simple creatures who were servants in the past have revolted and seized control of the Ark. Soon a plot to destroy the Ark and all it's human inhabitants is exposed but can they find the bomb in time?

The Celestial Toymaker

The TARDIS materializes in the Fantasy domain of the Celestial Toymaker, a jovial Mandarin who invites the Doctor to play some of his games. All too soon a darker side emerges and the Doctor, Steven and Dodo are soon fighting for their lives.

The Gunfighters

The Doctor and his companions arrive in Tombstone, a wild-west town in the late nineteenth century. They are soon to witness the infamous shoot-out at the OK corral.

The Savages

The Doctor and his companions arrive on a planet populated by two races, one very advanced (The Elders), one very backward (The Savages). The doctor soon suspects that all is not as it should be, and that the Elders are draining the life-force of the Savages to improve their own prowess.

The War Machines

A newly developed computer called Wotan hypnotises a number of people and starts building an army of machines with which to take over the world. The Doctor tries to alert the authorities to the danger but the message falls on deaf ears.
