Ron Gates, a young body builder, has several accidents while training with his manager, Artie Weaver, for the Mr. Galaxy title. The Angels are called in to find out who is trying to injure Ron. One of the suspects is the current Mr. Galaxy, Chuck Wilde. Another is Wilde's manager, Norman Powers. Another suspect is Danny Barr, owner of the arena with heavy underworld connections. At one time Ron Gates was a boxer who had a management contract with Barr, but who, after almost killing another boxer, quit boxing and took up body building. Barr has always been angry with Ron for walking out on him. Kris stays close to Ron to keep her eye on him. Kelly poses as a staff reporter for a leading body building magazine. Julie and Bosley are customers at the gym called Sportworld. Selena Hansen, the wife of the boxer Ron Gates almost killed, is also a suspect. Ron keeps away from all confrontations, and when Kris questions why he doesn't defend himself, he says he will never hit anyone again. Ron ultimately wins the Mr. Galaxy title. After several more brushes with death, the Angels discover it is Danny Barr who has been trying to get rid of Ron and he is taken into custody.
