Mitch Moran, a commercial flyer, partners with his younger brother, Steve, recently discharged from the U.S. Marines. Although Mitch plans to propose to his girl friend, Sally, she becomes enamored with Steve and promises to be his wife. However, Sally soon finds Steve to be irresponsible and resumes her romance with Mitch. As she is about to break the engagement, Sally receives word that Steve has been injured in a plane crash while performing stunts for a movie. She and Mitch agree that their love must be kept from Steve, who has lost his hearing as a result of the accident. Steve, however, learns of their sacrifice after they raise money for an operation that cures his affliction. He attempts to repay them by taking another stunt-flying job, but he is killed in the effort.
