Output: The film starts in a riverfront slum in Limehouse. The Lily Gardens, a local club, is owned by ChineseAmerican immigrant Harry Young. Young uses the club as a center of operations for his lucrative smuggling operation. Young is a recent arrival in London, but he has managed to take over crime operations in his area. Rival criminal Pug Talbot is increasingly driven out of business. Talbot is wrathful due to the situation, and his anger causes him to abuse his own daughter, Toni. The girl has been raised to be a pickpocket and is under her fathers control. At one point, Toni is about to be arrested, and Young helps her out. She is grateful for his help and grows very fond of him. Talbot alerts the police about one of Youngs operations, in hopes of hurting his rivals business. Toni overhears the plan and warns Young in time. Young manages to evade the police. Talbot is furious at his treacherous daughter and beats her up. Young finds out about the abuse and vows revenge against Talbot. Young pretends that he wants to negotiate with Talbot, and invites him for a meeting at his apartment. Talbot accepts the offer, unaware that it is a trap. When Talbot arrives from the meeting, Young has him stabbed to death. The corpse is abandoned in the street. Young offers Toni a job at his organization as a watchdog, in exchange for room and board. Toni takes the offer and gets hired. Young has a Chinese lover, Tu Tuan, that is suspicious over his relationship with Toni. She believes that her lover has fallen in love with the white girl and warns him against fruitlessly pursuing her. Worried that a jealous Tu Tuan might hurt Toni, Young removes the pickpocket from his operations. He gives Toni an allowance for her living expenses, which she sees as charity. Away from her life of crime and with free time in her hands, Toni goes sightseeing in London. She soon befriends petshop owner Eric Benton, and starts spending her afternoons with him. Toni and Benton fall in love. Toni starts thinking about getting a job to stop financially depending on Young. Young prevents her from doing so, in fear of losing her. Tu Tuan finds out about Tonis love life and warns Young about it. Tu Tuan derides Young for his unrequited love for a white woman, before ending her own relationship with him. Toni confesses to Benton about her criminal past. Benton visits The Lily Gardens and asks for an appointment with Young. In response, Young makes arrangements to have Benton killed, in a manner similar to Talbot. Young soon personally goes on a smuggling mission, and has Toni escort him. He is unaware that the police is expecting him this time. A distraught Tu Tuan had betrayed him to the police, before committing suicide. During the mission, Toni finds out about Youngs plans to have Benton killed. She is terrified for the safety of her loved one. By her reaction, Young realizes that Toni really loves the other man. He decides to call off the murder plans, and tries to warn his hired assassins in time. He is pursued by the police while trying to reach them, and gets mortally wounded by gunfire. Young calls off the murder in time, and manages to clear Tonis name from any involvement in crime. He then dies because of his wounds. Due to Youngs selfsacrifice, Toni and Benton are safe and free to further pursue their relationship.
