Sharon is an outstanding psychiatrist, and has a daughter named Jenny.

Her patients are mostly wealthy people and public figures. Sharon wants Jenny to meet a public figure named Mr. Lin. However, Jenny does not like Mr. Lin at all. Sharon forces Jenny to attend a banquet with Mr. Lin, but she doesn’t want to go out with Mr. Lin and has some unusual behaviours, she stands on a table and wets herself. It embarrasses Sharon and affects

her clinic business as everybody knows she has a mentally ill daughter.

Sharon does not think that her daughter is mentally ill. However, desperately, Sharon turns to an exorcist priest for help. The priest affirms that Jenny has been demon possessed. As a psychiatrist, Sharon never believes in any theories that are not scientifically proven. However, Jenny's condition is getting worse, Sharon is forced to choose between science and religious

belief.
