Following a skirmish in deep space, two alien spacecraft have crashlanded on a barren planet. The Drahvins are a race of beautiful females, led by the imperious Maaga. The Rills are hideous tusked monstrosities, accompanied by their robotic servants, the Chumblies.
When The Doctor arrives, he discovers that the planet will explode in two days’ time. The Drahvins desperately ask for his help in escaping the planet and the hostile Rills.
But things are not always as they seem.
