Description: Recovering consciousness after their speeding bullet car crashes into a steel bulkhead, Buck, Wilma, and Tallen return to the high tribunal of Saturn to plead their cause. Tallen has lost the filament-ray helmet that blotted out his mind, and again recognizes Buck and Wilma as his friends. Lasca discovers that the terrible primitive race, known as the the "Zugg" men, have accepted another human robot henchman of Lasca's as their leader and are staging a rebellion. Headed by Lasca and his gangsters they force their way into the forum. Buck smashed the radio set just as Lasca tries to broadcast for Kane to send reinforcements. The angry Zuggs charge Buck and he goes down under a wave of fighting animal-like creatures.
