A sailor who is a champion boxer in the Navy is forced to leave the service because his family's business, a tuna fishing operation, is in financial trouble. He becomes a prizefighter and one day signs up for a winner-take-all boxing match, which could make him a lot of money but could also result in the end of his boxing career.
