Queen X (1917)

In New York's notorious Pell Street district, U.S. District Attorney Arnold Somers' men capture Queen X, known to drug smugglers as "The Queen of Chinatown," a woman with a cross-shaped birthmark on her wrist. Summers recognizes her as Janice Waltham, formerly a prominent society woman. After becoming an addict and dealer, Janice was imprisoned in underground dens filled with opium fumes to prevent her from recovering and betraying her suppliers. She refuses to name her associates despite third degree questioning. As Janice is about to be sentenced to a long prison term, Miriam Evans, whose brother George is the assistant district attorney, recognizes Janice as the former schoolmate who rescued her in a convent fire. Somers allows Miriam to take Janice home and advises George to court her to get the names of the gang leaders. With George's help, Janice develops enough will power to kick her drug habit, while George, according to their pact, stops smoking cigarettes and drinking coffee. After George secures the names, Janice, threatened by a Chinese cohort, learns about George's deal, but George, now in love, confesses this and they marry.
