||Crooks Sliver and Turtle steal some atomic radium from the lab of Dr. Carol Topaze. In order to hide it they throw it into a cave at the zoo. As Dr. Topaze arrives, the crooks retrieve the radium. Jaguar Man, and Ja-Go pursue them across city roof tops as the crooks escape in a helicopter. When they finally land, Jaguar Man and Ja-Go attack, apprehend the crooks, return the radium to the doctor, and deliver the crooks to jail. Jaguar Man then resumes his secret identity as Murray Mane, zoo keeper.
