Zion, a girl who is constantly taken advantage of by her friends due to her shyness and timidity, is approached by two individuals who ask her strange questions about her belief in Confucian moral doctrine. In the end, she finds herself bowing and performing sacrificial rites to ancestral gods. It is shocking enough that the daughter of a pastor is possessed by a ghost, but even more shocking is that this ghost is a young oppa whose fashion sense surpasses the outstanding looks of most bachelors and rockers. From this day on, Zion’s life changes forever. She transforms from a shy and unsuspecting high school student into an exorcist.
