Synopsis by Hans J. Wollstein
French director Maurice Tourneur's final film before relocating to America, this two-reel drama featured vaudeville star Polaire in the title role, a foundling who grows up to become a milliner. She falls in love with an idealistic young doctor, Paul (Henri Roussell), but their romance is interrupted with the discovery that her long-lost father has become an important and wealthy man. There is an ambitious stepmother (Renée Sylvaine), who attempts to break up Soeurette and Paul, but everything is worked out in the end. Soeurette, which apparently has not survived, was based on a 1902 novel by Gyp, a notorious French author who in reality was Sibylle de Mirabeau, the Countess de Martel de Janville.
