Jewel thief Madeleine (Dietrich) manages to involve innocent tourist Tom (Cooper) into carrying her ill-gotten goods across the Spanish border. Then she entices him into joining her at the country estate of her partner-in-crime. By this time Tom is in love--and so is Madeleine but she doesn't think she's good enough for him. Lots of lying until the twosome can figure out what to do. Cooper manages to hold his own with the sophisticated Dietrich in their second film together (after "Morocco").
