Though magazine publisher Van Stanhope (Clark Gable) and his wife, Linda (Myrna Loy), are contentedly married, Van's meddling mother (May Robson) doesn't trust his attractive young secretary, Helen "Whitey" Wilson (Jean Harlow). When Whitey helps Van undertake a top-secret plan to purchase a potentially profitable magazine from under the nose of a rival publisher, causing the pair to work long hours alone together, Linda's sudden jealousy almost scuttles both the deal and their marriage.
