Midnight Mary (1933)

A young woman is on trial for murder. In flashback, we learn of her struggles to overcome poverty as a teenager -- a mistaken arrest and prison term for shoplifting and lack of employment lead to involvement with gangsters. In a brothel, she meets a young lawyer, scion of a wealthy and prestigious family, who falls for her and helps her turn around her life. But her past catches up with her, and she must face the music rather than cause him scandal.
