Triple Trouble

Five friends, Slip, Sach, Whitey, Butch, and Chuck, are arrested for a warehouse robbery and later released on bail. After learning that the robbery instructions may be coming from a prison inmate via short-wave radio, they go on trial. Slip and Sach plead guilty, while the others receive probation. In prison, Slip and Sach pose as notorious gangsters Pretty Boy Gleason and Benny the Blood to gather information on the robbery instructions. They meet the leader, Bat Armstrong, and learn of a planned prison break. However, the real Pretty Boy and Benny are soon imprisoned, and Slip and Sach are exposed as impostors.
