This hilarious three-reel farce from director Ernst Lubitsch stars Ossi Oswalda as Ossi, a vivacious young woman whose ideas of fun -- smoking cigarettes, playing cards, dating boys -- unnerves her stodgy Uncle (Ferry Silka) and even stodgier Governess (Margareta Kupfer). When Uncle has to go to America on business, he hires the stuffy young Dr. Kersten (Kurt Goetz) as her guardian. Tired of being sheltered, Ossi disguises herself as a man and goes out to a nightclub. As a man, she endures some rough treatment from both women and other men, but her masquerade enables her to become drinking buddies with none other than Dr. Kersten, who can't refrain from cuddling and kissing his handsome acquaintance! A cab driver mistakenly takes the two drunks to each other's houses, and Ossi, still in drag, encounters Dr. Kersten when she sneaks back into her own home. He then catches her changing out of her disguise and embraces Ossi as his new love.
