Gambler Babe Stewart (Clark Gable) flees Manhattan when his mistress threatens to turn him in. He hides out in a small town, where he meets prim librarian Connie Randall (Carole Lombard). When Connie refuses his advances, Babe impetuously flips a coin to decide whether to marry her, and does. Returning to New York with Connie, Babe avoids the police and convinces his new wife that he holds a respectable day job. But when Connie discovers Babe's duplicity, she takes matters into her own hands.
