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 fiancee, 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.
Every summer, Mrs. Prentiss produces a charity show for the "Milk Fund", and this year she hires the flamboyant and conniving Russian dance director Nicolai Nicoleff (Adolphe Menjou) to direct the show. The parsimonious Mrs. Prentiss wants to spend the least amount possible, but Nicoleff and his set designer Schultz (Joseph Cawthorn) want to be as extravagant as they can, so they can rake off more money for themselves, and for the hotel manager (Grant Mitchell) and the hotel stenographer (Glenda Farrell), who's blackmailing the hapless snuffbox fancier Thorpe.
Of course, Dick and Ann fall in love, Humbolt marries Arline, and the show ends up costing Mrs. Prentiss an arm and a leg, but in the end she realizes that having a doctor in the family will save money in the long run.
