An innocent but admittedly none-too-bright victim of circumstance, Mary Burns (played by perennial movie victim Sylvia Sidney) is inexorably sucked into the vortex of organized crime. She tries to escape her murderer husband Babe Wilson (Alan Baxter), but it's a losing proposition, especially since the newspapers have already branded her a gun moll. Making matters worse, she is thrown into prison for crimes committed by her husband (understandably, since her behavior at her trial was self-defeating to say the least). Though believing her guilty, detective Harper (Wallace Ford) allows Mary to escape from jail, hoping in this way to track down Wilson. Nominal hero Alec MacDonald (Melvyn Douglas) isn't much help; not introduced until the film's halfway point, he spends most of his time in a hospital bed, recuperating from an injury. In fact, the story is wrapped up only after MacDonald is rescued by the heroine!
