The TARDIS brings the Doctor, Zoe and Jamie to the planet Dulkis, which the Doctor knows as a peaceful world that has abandoned war. But the travelers find themselves on an island strewn with the remnants of an ancient war and contaminated with radiation – the legacy of nuclear weapons tests, according to a small number of researchers encountered by the Doctor. What the Time Lord doesn’t realize is that the native Dulcians are not the only people visiting the island. Another Dulcian expedition meets with disaster, its only survivor claiming that his shipmates were killed by well-armed robots. The Doctor and Jamie go to investigate these claims, and find themselves taken prisoner by a group of aggressive aliens who call themselves the Dominators. These would-be invaders, backed up by their powerful Quark robots, intend to mine the radioactive minerals on Dulkis to make their own nuclear weapons…and they also wish to use the pacifist Dulcians as their slaves. The Doctor scrambles to find a way to undermine the Dominators when it becomes obvious that the Dulcians are unwilling to rediscover the aggression necessary to protect themselves.
