Li Jianguo, a community security guard who is nearly 50 years old, is despised by his property owners because he has accomplished nothing. During a patrol, he picked up a bronze medal engraved with the word "Suppress Evil" and accidentally awakened to the lost Taoist talismans. It turns out that the community was built on top of an ancient tomb, and the evil spirit was so pervasive that the residents encountered strange things one after another. From then on, Li Jianguo guarded the community during the day and used talismans to kill evil spirits at night. He transformed from a "waste" to a guardian respected by the neighborhood.
