Description: Righting his rocket ship as it falls dizzily toward earth, Buck makes a safe landing, but he and Wilma are captured and taken to Kane's palace. The Hidden City people believe Buck has been killed, but Buddy Wade refuses to accept the thought. Risking his life to save his friend, he drops from a plane and lands inside Kane's airdome at night. Finding the council chamber in the palace empty, he reads the television machine and locates Buck inside the dynamo room. Buck is wearing a filament-ray helmet that makes him a ehlpless human robot and slave. Just as Buddy starts from the room to free Buck, a guard discovers the boy and shoots him down as he leaps through a window, apparently to his death.
