Four Walls

Benny Horowitz, an East Side gang leader, kills another gangster in self-defense and is sentenced to prison on the charge of manslaughter. Having served out his term, Benny decides to go straight and finds work in a garage. His old girl, Frieda, wants to resume their former intimacy, but although he still loves her, Benny turns instead to Bertha, a plain girl who befriended his mother while he was in jail. He later attends a party at which Monk, the new gangleader, is accidentally killed in a fall. Sullivan, the detective who sent Benny up the first time, at first suspects him of having murdered Monk; eventually Benny is cleared of suspicion, inviting Frieda to share a new life with him.
