According to "The New York Times", the film became a "star vehicle" for Song. The film was about an average, popular Chinese-American teenager whose life is turned upside down by a visit from a young Chinese monk (Shin Koyamada). The monk claims she is the reincarnation of a powerful female warrior and the only person who can prevent an ancient evil spirit from destroying the world. In a second story line, Wendy and most of her family struggle with keeping their culture and heritage. Song felt she could relate to the message since she knew little about her own people before making the film. She said, "I really identified with Wendy because I don't want to not know where I came from". To promote the film, she posed for the cover of "Seventeen", "Teen People", "Teen", "Seventeen" Malaysia, and several other magazines, and traveled to Malaysia, Singapore, and Costa Rica. A "Wendy Wu: Homecoming Warrior" sequel, starring Song and Koyamada, was announced in the end of 2007.
