A doctor-turned-priest, Father Park was excommunicated for performing exorcisms by a church that refused to believe in the supernatural beings preying on the innocent. When his long-time friend, a monk from a secretive and magic-wielding temple, calls upon him to protect a naïve yet powerful child from his corrupt master, Father Park must face his inner demons to rescue the boy or risk repeating the same tragedy that he took up the cross to prevent.
Two orphans, Gamie, a young blind girl and her little brother Gil-sun, are taken in by a Buddhist monk. While the shy little girl finds her at ease at the temple, the enthusiastic and dynamic little Gil-sun soon starts to disturb this quiet place. After his sister told him their mother had visited her in a dream, the little boy tries to understand why his mom did not come to see him too. In order to meet her again, he decides to follow the monk for a very long initiatic trip.
