Jim is a truck driver who aspires to be a champion boxer. One day he gives a ride to Peggy, who is down on her luck, and she agrees to meet him for a date after she hears of his future plans. That night, Jim confides in his best friend, Tony, that he has met someone, then goes to train at a gymnasium. After Peggy gets off work as a switchboard operator the next day, she goes to Tony's shoe repair shop to have the heel fixed on her shoes. While repairing Peggy's shoe, Tony tells her about Jim, who is like a son to him, but neither knows they are talking about her date. Peggy is late in meeting Jim, while Jim arrives at the building Peggy pointed out as her apartment, but discovers it is a funeral parlor, and leaves disappointed. Still unaware of their previous encounter, Tony arranges for Peggy and Jim to meet, and they fall in love after confessing that they both kept their first date. With Tony acting as his manager, Jim gets a chance to fight a famous heavyweight, and although Jim is beating him, Tony stops the fight early. This mistake prompts much publicity, and Jim is next slated to fight the murderous fighter Pico Vacci. Peggy argues with Jim not to go through with the fight, and as a result, he breaks up with her. Pop Henley, a representative of Madison Square Garden, attends the match between Jim and Vacci, and although Jim is brutally beaten and loses, Henley wants to book him at the Garden. Jim feels utterly defeated and refuses, but then Peggy arrives, having heard the fight on the radio. Peggy apologizes for her prior misgivings and, soothing his wounds, accepts Henley's offer for Jim, proudly proclaiming that Jim will be a champion.
