In the resort of Lake Waxapahachie, the swanky Wentworth Plaza is where the rich all congregate, and where the tips flow like wine. Handsome Dick Curtis (Dick Powell) is working his way through medical school as a desk clerk, and when rich, penny-pinching Mrs. Prentiss (Alice Brady) offers to pay him to escort her daughter Ann (Gloria Stuart) for the summer, Dick can't say no – even his fiancée, Arline Davis (Dorothy Dare) thinks he should do it. Mrs. Prentiss wants Ann to marry eccentric middle-aged millionaire T. Mosley Thorpe (Hugh Herbert), who's a world-renowned expert on snuffboxes, but Ann has other ideas. Meanwhile, her brother, Humbolt (Frank McHugh) has a weakness for a pretty face: he's been married and bought out of trouble by his mother several times.
