Boston Blackie, just released from prison, threatens the warden, Benton, that he will have him removed from his job for using the water cross, a form of torture, on prisoners. Blackie's sweetheart, Mary Carter, helps him avoid this torture after his return to prison. The officers pursue Blackie, capture him, and bring him back to Benton, but Mary reports to the governor, and they arrive in time to save Blackie from further torments by bringing his pardon. Benton is fired.—AFI
