Boston Blackie is a former prison inmate campaigning to outlaw Warden Benton's infamous "Water Cross" torture. Benton, however, is successful in his attempt to have Blackie arrested and returned to the prison, but his evil schemes are ultimately thwarted by Mary Carter, Blackie's girlfriend, who manages to alert the governor. Considered a lost film.
Unfortunately the movie Boston Blackie is not yet available on HBO Max.
