Colony In Space

The Master has stolen a file from the Time Lords, and in an attempt to retrieve it the Time Lords send the Doctor and Jo in the TARDIS to the planet Uxarieus in the year 2472.

During their time on the planet they become involved in a dispute between colonists and the Interplanetary Mining Corporation over the ownership rights of the planet. The Master arrives in the guise of the Adjudicator sent from Earth to take charge of the situation.

The Doctor learns that the natives worship a machine tended to by the Guardian. The machine is in fact the doomsday machine, responsible for recent crop failures, and the decline of the Guardian's race.

The Master plans to seize the doomsday machine, which is capable of destroying whole planets. The Doctor managed to persuade the Guardian to destroy the weapon rather than let it fall into the hands of the Master.
