A mob leader escapes prison and flees with his love to a mountain hideaway, where he tries to atone for his sins.

In a prison hospital ward, dying gangster Duke Berne tells Warden Booth and two young people, George Anderson and Ruth Carter, the story of his recent past: Knowing that as a three time loser, he will be sentenced to life in prison if he is arrested again, Duke decides to go straight. He is unable to get a job, however, and is totally broke when crooks Frenchy and Sander invite him to join them in a robbery set up by wealthy lawyer Martin T. Fleming. Initially Duke is not interested in the job, but pays a visit to Fleming's office to look into it. There he is introduced to Fleming's wife Lorna, who, unknown to Fleming, is Duke's former lover. Duke agrees to carry out the robbery. Later, Lorna, who broke off with Duke when he insisted on going through with the robbery that sent him to prison, visits his room and begs him not to do this job, promising to come back to him. Impressed by the intensity of her feeling, Duke agrees to back out of the job. The robbery fails and only Frenchy escapes with his life. The police are convinced that Duke was involved and persuade a witness to falsely identify him as the man who held her hostage after the robbery. Lorna wants to tell the police that she was with him during the crime and thus provide him with an alibi, but Duke does not want her to be exposed to a scandal. Instead, he asks Fleming to provide him with an alibi and threatens to reveal his complicity if he does not cooperate. Fleming hires George Anderson, who needs the money in order to get married, to provide Duke's alibi. With Fleming as his lawyer, Duke is set to go to trial when Frenchy contacts Fleming and tells him that Lorna was with Duke during the robbery. After George testifies that he was with Duke, the prosecution, with Fleming's secret help, introduces a new witness, George's fiancée Ruth, who, not knowing that George has lied about his activities, testifies that George was with her the night of the robbery, thus proving that George is lying. Duke receives a life sentence, and George is sentenced to a year in prison for perjury. On a prison visit, Ruth gives George a message for Duke from Lorna, telling him that she has left her husband. Duke then plans a prison break, aided by Lorna, who places the necessary tools under the warden's car. During a prison show, Duke and another convict break out and George tries to stop them. The other man is killed but Duke escapes over the wall where Lorna is waiting. When one of the guards dies, George is charged with his murder, despite his honest statement that he was not trying to escape. Fleming discovers Duke's hideout and sends the police after him. In the meantime, Duke learns of George's murder charge and knows he must clear him. He and Lorna leave just as the police arrive and a chase ensues. Lorna is killed during the chase, but Duke manages to get to Fleming. Holding him at gunpoint, Duke calls the warden. Fleming shoots Duke and Duke returns his fire. Fleming is killed and Duke is fatally wounded, but before he dies in the hospital, Duke clears George's name.
