Based on a book by San Quentin ex-con Malcolm Braly, this tough, violent prison movie depicts the power struggle that ensues when a con artist (John Heard) behind bars for murder dares to undercut the terms of his agreement with a recognized gang leader (Thomas G. Waites) in charge of the cigarette trade. This hard-nosed story is a suspense-laden film in the tradition of the great penitentiary dramas. Mike Kellin, Lane Smith co-star. 102 min.
