1940s film noir starring Laraine Day and Robert Mitchum. Just before he is due to marry Nancy (Day), John Willis (Gene Raymond) is approached by her first husband, Harry Blair (Brian Aherne), who informs John about his ex-wife's sordid past. Harry explains that before he married Nancy, her former lover, Norman Clyde (Mitchum), told him that she was a thief and a liar, and even worse, had played a part in a murder. As he had thought Norman was jealous, Harry had not believed him. But is it Harry who is jealous? Is he telling tales to prevent his ex-wife from marrying again, or is Nancy really a dangerous woman?
