You Can't Beat the Law is a 1943 American drama film directed by Phil Rosen; also known as Prison Mutiny (American TV title).

Plot

Johnny Gray (Edward Norris) is a self-proclaimed playboy. Gray's car is found at the scene of a crime; and although it's been stolen, it is enough to convict Gray of the holdup. Rico (Willy Castello) is the real criminal, but never becomes a suspect. Rico's gang members Creeper, Harry, and Red are also sent to jail with Gray. When Gray's fiancée even believes Johnny is guilty, he becomes angry and a difficult prisoner. Gray is eventually put in the same cell as Cain (Jack La Rue); who is the head of a gang that's planning a prison break. Frank Sanders (Milburn Stone) is a new warden at the prison, and he eventually earns Gray's trust. Gray is transferred to different cell with a new cell-mate, and given the chance to work in the prison gardens. While working in the gardens, Gray meets Amy Duncan (Joan Woodbury), who is the daughter of one of the prison guards. Rico plans a prison break from the outside, but is killed in the attempt. Eventually one of Rico's men admits that Johnny Gray is an innocent man.
