Everyone knows that Pluto is a barren airless rock. So naturally the Doctor is surprised when he discovers artificial suns, an ultra-modern industrial city and a group of colonists being worked - and taxed - to death in this inhospitable and supposedly undeveloped part of the universe....

With the help of his companion Leela and the faithful K9, the Doctor takes on the mysterious and powerful Company, ruthless exploiter of planets and their people.

The planet Chloris is very fertile, but metal is in short supply, and has therefore become extremely valuable.

A huge creature, with most unusual physical properties, arrives from an alien planet which can provide Chloris with metal from its own unlimited supplies, in exchange for chlorophyll.

However, the ruthless Lady Adrasta has been able to exploit the shortage of metal to her own advantage, and has no wish to see the situation change.

The Doctor and Romana land on Chloris just as the creature's alien masters begin to lose patience over their ambassador's long absence.

The action the aliens decide to take will have devastating consequences for Chloris, unless something is done to prevent it...

His spaceship crippled in an inter-stellar battle, the Sontaran warrior, Linx, is forced to crash-land on earth. He arrives in the Middle Ages, a time too primitive to provide the technology he needs to repair his ship. Allying himself with the local robber chief, Linx uses his powers to 'borrow' scientists and equipment from twentieth-century earth.

Doctor Who tracks down the missing scientists and journeys into the past to save them. But can he defeat the ruthless Linx and his savage human allies before the course of human history is changed forever?
