Stung by the injustice, when even his fiancee (Inna Gest) believes him guilty, Johnny becomes an unruly prisoner and is put in a cell with Cain (Jack La Rue), head of the prison gang planning a break. The new warden, Frank Sanders (Milburn Stone), wins Johnny over by changing his cellmate and giving him a chance to work in the prison gardens. Here, he meets Amy Duncan (Joan Woodbury), daughter of prison guard Duncan (Robert Homans). In an failed escaped, engineered from the outside by Rico, who is killed, one of Rico s men confesses that Johnny is innocent.
