Shame (1921)

While living in Shanghai with his young son David, William Fielding is close friends with his secretary, Li Clung, after the death of his wife. Foo Chang, a trader, loves the young woman who cares for young David and kills Fielding when he assumes that she is the boy's mother. Li Clung takes the child to his grandfather in San Francisco, where he grows up and inherits the Fielding estate. Following David's marriage, Foo Chang tries to bribe David to help him bring a cargo of opium into the city, informing him that he is a half-caste. Without waiting to learn the truth from Li Clung, David takes his infant son and goes to Alaska. He is followed by his wife and his faithful servant Li Clung, who kills Foo Chang and explains that David's mother was not Chinese. Brought to his senses, David returns with them to San Francisco.
