Ah Dai comes from a family that runs a prestigious orthodox temple. His childhood sweetheart, Yufan, is desperate to locate her missing aunt. In his attempt to help, Ah Dai agrees to participate in a special ritual that his schoolmates believe could help them seek assistance from the gods to grant their desires. However, they are lured into praying to evil forces instead. As his schoolmates die one after another, Ah Dai tries to use his gift to exorcise evil to save his friends. At the very end, he faces a completely demonized Yufan and must fight her to save the neighborhood.
