Slip, Sach, Whitey, Butch and Chuck witness a warehouse robbery, and are arrested and jailed on suspicion. Gabe Moreno, their lawyer-friend gets them released on bail. Since the charge of suspicion is one that the prosecutors appear to believe can be easily proved, the gang is awaiting trail, when Whitey, a short-wave radio fan, picks up information that leads him to believe that instructions for the warehouse robbery and others are given by an inmate in the penitentiary to his pals on the outside via short-wave radio. When the five go on trail, Slip and Sach plead guilty so that they may be imprisoned and the other three are given probation.
