An alien craft bearing the ruthless Dominators arrives on the peaceful planet of Dulkis. The craft lands on the Island of Death, a nuclear test site housing an anti-war museum, and soon absorbs all the radiation on the island. The robotic Quarks are sent out by the Dominators to prepare boreholes into the planet’s crust in order to convert the planet into rocket fuel. Toba uses the Quarks to fire on and kill three adventure seekers who stumble across his project. Their pilot Cully, however, survives by hiding, though the craft that brought him to the island is destroyed. Rago is furious that these potential slaves have been wasted.
