"Now it can be told! Opium dens buried in San Francisco alleyways! Virgins seduced into unspeakable Chinatown pleasures! This 1915 Paramount 5-reeler stars Blanche Sweet in a trick-photography dual role as twin daughters of impoverished parents. While their father seeks his fortune in the oil fields, Sessue Hayakawa, the Chinatown 'hop joint proprietor,' provides handsome temptation; and soon dope addiction-a popular exploitative subject in the 'teens-claims the weaker of the two sisters. Even for the year the direction is rather primitive, but the film has a keen feel for the sweatshop milieu, as well as something of the unpredictability that makes the first feature films such revelations."
