With its racy title and emphasis on jazz parties and youth, this romantic drama was a typical mid-'20s release. But being an early release from the newly formed MGM, it also featured a great cast, headed by the suave Adolphe Menjou. Menjou plays Arthur Merrill, whose fast lifestyle has made him old before his time. Through Dr. Eustace (Jean Hersholt) and the miracles of modern medicine, he is able to obtain a rejuvenation treatment which restores his lost youth. Merrill has met thoroughly modern flapper Penelope Stevens (Eleanor Boardman) and wants to win her. After he lures her to his apartment and discovers that she's a "nice girl," he can't help but give her a fatherly lecture for her behavior. Then it turns out he really is a father; Brock Farley (Conrad Nagel) arrives from Ohio with a letter proving that he is Merrill's son. Penelope and Farley fall in love, and Merrill decides he's better off acting his own age.
