Jiushu (Lin Zhengying), a Taoist priest with a single eyebrow, is good at exorcising demons and monsters. His two apprentices, Axing (Ni Xing) and Xiaoyue, are mischievous and often do things that give their master a headache. A bizarre tragedy happened in the Jiuquan Town Church where Jiushu and his apprentice worked. The cross on the roof was struck by lightning, impaling the priest to death. The church has been abandoned and closed since then. Twenty years later, Father Wu (Wu Ma) planned to reopen the church. Jiushu knew that the church was in the most yin place in Jiuquan Town, and reopening it would hurt lives, so he strongly opposed it.

However, since then, the evil spirit inside has returned to the world...
