A gullible and honest "Mr. Universe" winner, Tommy Tomkins, gets added to the stable of a con-man and a wrestling prompter. He wins match after match, legitimately, and then balks when he is told he must lose a match, as all in the phony-sport of professional wrestling must do at one time or another.A complication arises when Tommy can not be taught to be dishonest. Complications also arise when a gangster tries to buy in on the setup. A "comedy" film based on the tragic career of prizefighter Primo Canera.
