Among the Baojiaxian worshiped by a certain family in the Northeast, there are descendants of the Hu family (fox) who have been practicing for nearly a hundred years. She has a clear temperament, with a bit of innocence still intact, but she also abides by her duty of "keeping the family and home safe and receiving incest from the world." When the descendant of the family she enshrined (a young girl working outside the home) returned to her hometown, the long-uninhabited peace of the old house was broken. Old grudges and obsessions hidden in the house, alleys, and even the surrounding mountains, forests, and rivers began to emerge. As the "fairy" who protects this place, she "Family", he must not only protect the descendants of this family, but also deal with these supernatural entanglements that have arisen due to the backlog of time. In the process, he also gradually reveals the relationship between his family and the ancestors of this family, as well as a forgotten past event on the road of spiritual practice.
