American architect Robert Lomax (William Holden) is living in Hong Kong for a year to try and make a living as an artist. While aboard a ferry, he meets Mi-Ling (Nancy Kwan), a smartly dressed young woman who claims her father is wealthy. When the ferry docks, they part ways. Robert looks for an inexpensive living place in
Wan Chai, a poor area known for prostitution. By chance, he sees Mi-Ling leaving the run-down Nam Kok Hotel. When he inquires inside, the hotel owner replies that he does not know any Mi-Ling, but he and Robert negotiate a monthly room rate. At the bar adjoining the hotel, Robert sees Mi-Ling dressed in a slinky red
cheongsam and with a sailor. He learns her real name is Suzie Wong, and she is the bar's most popular girl. The following day, Robert visits a Western bank and sets up an account with banker Mr. O'Neill, who also provides him letters of introduction. His secretary and daughter, Kay (Sylvia Syms), is immediately attracted to Robert. Robert hires Suzie to pose for him. He eventually learns that she was forced into prostitution after being abandoned when she was ten. Suzie begins falling in love with Robert, but he dissuades her, though he keeps her as his muse. Meanwhile, Kay discreetly pursues Robert. One night after a party at Kay's house, Robert invites her to see his paintings but is embarrassed to find Suzie on his bed. After Kay departs, Robert orders Suzie out. As she is leaving, a sailor whom she spurned earlier that evening beats her in the stairwell. Enraged, Robert punches the sailor. Suzie accepts her client Ben's (Michael Wilding) offer to be his mistress to make Robert jealous. When Ben reconciles with his wife, he asks Robert to tell Suzie the news. She is so hurt by the rejection that Robert finally admits he loves her and asks her to stay with him. Soon the couple is living together in the hotel, with Robert painting more enthusiastically than ever. Curious about Suzie's daily absences, he follows her up a hillside path to a small house. He finds Suzie visiting her baby son, whom she has kept secret. Robert accepts the child. Robert faces financial difficulties when his paintings fail to sell. Both Kay and Suzie offer him money, but he refuses. When Suzie pays his rent and wants to resume working as a prostitute to help him, he angrily drives her away. Robert quickly regrets his actions and spends days searching for Suzie. Meanwhile, Kay informs Robert that a portrait of Suzie has sold in London. Robert reveals that he has lost Suzie. Kay, misunderstanding, says he can find another model; she romantically pursues Robert but he rebuffs her. Robert finds Suzie waiting outside the hotel. She asks for his help to retrieve her son, who is in danger due to the heavy rains. Robert and Suzie force their way up the hillside house, but the baby has been killed by a landslide. After the funereal temple ceremony for her son, Robert asks Suzie to marry him. She agrees. ==Cast==
