The Return of Boston Blackie

A girl seeks revenge after a Wall Street broker had falsely accused her father and sent him unjustly to prison.

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.

While burgling a mansion, Blackie is interrupted by little Joey, who has been awakened from his slumbers. Blackie gently orders the kid to return to bed, but Joey refuses to do so unless Blackie helps him say his prayers. Thus is formed a strong friendship between Blackie and his "little pal," inspiring our raffish hero to rescue Joey's mother Rosemary Theby from a scandalous situation.

A German Shepherd puppy is "adopted" by a wolf pack in the snowy and frozen Great North and raised by them as one of their own.
