While taking a morning workout, young prizefighter Danny Martin encounters Charlotte Hamilton in distress over her balky roadster. Martin wins his fight but is counted a loser by a crooked referee. Later, he is invited to a barbecue at Charlotte's home, but when John Hamilton, who strongly dislikes fighters, learns of Martin's profession, he shows him the door. Danny gives up his career for Charlotte and opens a health resort for obese millionaires. Hamilton and his prospective son-in-law, Penrod, arrive at the resort for treatment, and their indignation and disgust at the treatment provide comic complications. Learning that Danny and Charlotte have already eloped, Hamilton is at first furious, then resigns himself to their happiness.
