Prison Shadows on AllMovie

Prison Shadows was put together by the Mercury Productions division of Puritan Pictures, the same folks responsible for the above-average horror thriller Rogue's Tavern. Eddie Nugent plays rising young boxer Gene Harris, who is thrown into jail on a manslaughter charge after one of his opponents dies in the ring. Out on parole, Gene can't get over the fact that he has blood on his hands and is reluctant to climb back into the ring. But his crooked manager has already exploited Gene's grief by advertising him as "Killer" Harris, so our hero figures he's got nothing to lose. Reluctantly, he agrees to another fight -- and once again, his opponent is killed. By this time, the audience is way ahead of Gene in suspecting that there's some sort of criminal conspiracy going on, with the luckless boxer pegged as the fall guy.
