Yu-jin and her blind mother move to a small village from Seoul. On her first day at the new school, Yu-jin gets picked on by her classmates. Along with other victims of hatred, Yu-jin puts a curse on the four girls tormenting them through a Ouija Board. On her second day at school, one of the spellbound bursts into flames and dies just as she sits down where Yu-jin used the board. Next day, another victim burns to death, and now the school is enclosed by horror.
