Bradshaw, an Englishman, is arrested for the New York killing of booze racketeer Buck Cooly. Interrogated by police chief Galvin, Bradshaw claims self-defence, but refuses to name the woman he was with at the speakeasy where Cooly was shot, and who could provide the alibi that would exonerate him from a murder charge. Galvin's continued pursuit of the woman's identity eventually leads to an unwelcome surprise.
