Against the wishes of his law partners, lawyer Andrew Morton (Humphrey Bogart) takes the case of Nick Romano (John Derek), a troubled young man from the slums, partly because he himself came from the same slums, and partly because he feels guilty for botching the criminal trial of Nick's father years earlier (he was innocent). Nick is on trial for viciously killing a policeman point-blank and faces execution if convicted (the event is shown in a dark opening scene, but the killer's face is not seen).
