Having invented the TARDIS, a strange machine capable of travelling into other dimensions, the Doctor and his three young companions, set forth on a quest through time and space.

Their journey takes them into the dark, undiscovered depths of the universe and to the planet of Skaro; a primitive world devastated by nuclear war and populated by two warring species, a peaceful tribe, known as Thals and a life form heavily mutated by radiation, encased in protective machines, a merciless force of destruction known as The Daleks!
