Commando Cody captures one of The Ruler's officers and forces him to call The Ruler to the planet Mercury--which his forces occupy--using his own spaceship as bait to entice The Ruler to come; Cody then plans to end the menace of The Ruler once and for all. He discovers a resistance group on Mercury, but at first they're suspicious of Cody's motives, and he must convince them of his real intentions in order to enlist their help in capturing The Ruler.
