San Quentin inmate Jack Palance hatches quite a scheme to get out of jail--get his lookalike brother to trade places with him in prison for a day while he constructs a foxhole to hide in, leading to his and his brother's escape. Filmed on-location in Cinemascope at San Quentin prison, with officers and inmates used as extras. It's a ludicrous plot, but the director keeps everything very low-keyed, and Jack Palance is excellent in demanding dual role. Extraordinarily silly, but so well-made you may be absorbed and interested despite yourself. Harold Stone is steely-eyed and cunning as a prison guard and Edward Platt(later of TV's "Get Smart")is believably sympathetic as the nicest prison warden you'll ever see. Barbara Lang also good as the convict's wife, obviously cast for her platinum hair and curvy figure, but giving a grounded, natural performance without showy airs.
