Tim, a rookie policeman, becomes engaged to Mary O'Neill, whose brother is mixed up with a gang of car thieves. One of the gang, Red Mike, makes himself obnoxious to Mary (who had once rejected his marriage proposal), and Tim beats him in a fight. To gain revenge, Mike frames Tim's father, Pat, for murder, and Tim takes the blame. Tim is released on bail and through Mary's brother learns that Mike was behind the frameup. He brings the gang to justice, is reinstated on the force, and marries Mary. Uprav informace o filmu
