When ghosts must compete to survive in the underworld by haunting the living, one unassuming young woman needs help creating a lasting performance while under the tutelage of a passionate agent and a washed-up diva.

High school student Li Chih-hui worships martial arts movie star “Long” and dreams of becoming a kung fu master so he can defend himself from bullies. When classmate Chien Li-hua shows concern for the bullied Chih-hui, he begins to develop feelings for her. And when he finds out Li-hua is into divination and wants to become a spirit medium, Chih-hui pens a script entitled “Long and the Magic Princess” and invites her to star in it, but the bullies show up and knock Chih-hui unconscious. When he wakes up, however, Chih-hui suddenly declares that Long’s spirit now possesses his body.
