Folklore researcher {Gu Qingci} returned to the empty coffin courtyard of his old home to investigate the centuries-old legend of his hometown Gujia Village. The dozen or so empty coffins in the courtyard are extremely strange. When someone dies in the village, one of them will automatically close, but when the coffin is opened, there will be nothing. Lu Qingci, who lived in the old house, was disturbed by the sound of coffins opening and closing every night, and he frequently saw old people wearing shrouds wandering around the courtyard looking for them. As the investigation deepened, she accidentally discovered that there was a secret room hidden under the empty coffin courtyard. The memorial tablets of the Gu family ancestors in the secret room completely overlapped with the list of missing persons in the village over the years. The dust-laden secret was revealed - the ancestors of the Gu family once sacrificed human beings in exchange for the prosperity of the family, and the empty coffin was a container that sealed the souls of the sacrificers. Now that the seal is loose, the revenge of the dead souls is imminent, and Gu Qingci, a descendant of the sacrificer, is the only key to unlocking the seal.
