Daughter of the Dragon is a 1931 American pre-Code crime mystery film directed by Lloyd Corrigan, released by Paramount Pictures, and starring Anna May Wong as Princess Ling Moy, Sessue Hayakawa as Ah Kee, and Warner Oland as Dr. Fu Manchu (for his third and final feature appearance in the role, excluding a gag cameo in Paramount on Parade).

Fu Manchu is thought to have died twenty years ago, wrongly believing that Sir John Petrie was responsible for the death of his family during the Boxer Rebellion.

Ah Kee, a Chinese detective working with Scotland Yard tells Sir Basil Courtney that Fu Manchu is still alive and he has just seen him.

The mortally wounded Fu Manchu escapes and meets Ling Moy, making her take an oath as his son to avenge his and their family's deaths.

Ling Moy befriends Ronald, intending to kill him, yet they start to develop a romantic interest despite his engagement to Joan Marshall.

Ling Moy finds she is unable to kill Ronald as she loves him, and the henchmen are unhappy with her not acting as the son she had declared to Fu Manchu she would be.

Ah Kee discovers Ronald is in the building and realizes Ling Moy is duping him, and refuses to drink wine he knows is poisoned.
