Pride of Sunshine Alley (1924)

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 frame-up. He brings the gang to justice, is reinstated on the force, and marries Mary.
