Billy, a jockey, and Jim, an assistant manager of a New Orleans racetrack, are close friends. They become bitter enemies because of Marie, an unprincipled young woman who marries Jim after betraying her first fiancé, Billy, on their wedding day. Marie's extravagance causes Jim to steal money from the office safe and to bet on Billy. Billy wins, but Jim is arrested and sent to jail when Marie neglects to replace the stolen money. Jim serves his term and is reunited with Billy after Marie and her lover are turned out of the house.
