Waitress-turned-Broadway star Mabel O'Dare (Marion Davies) and garage-mechanic-turned-prize fighter Larry Cain (Clark Gable) dislike each other intensely, but press agent Aloysius K. Reilly (Roscoe Karns) cooks up a phony romance between them for publicity. Inevitably, the two fall in love for real, and plan on getting married, with Mabel quitting show business to be a housewife and Cain quitting the fight racket to run garages in New Jersey.
