In order to investigate the seven mysterious disappearances in the "Wugui Village" in the past ten years, reporter Wei Ran entered this almost isolated mountain village under the pretense of visiting relatives. The village is filled with thick fog and taboos are everywhere. There are always paper figures walking around at night and the sound of ritual drums is faint. He heard the cryptic phrase "sacrifice a living heir" from the half-mad old witch Zhu Honggu. As the investigation deepens, the secret connections between the missing people emerge, and the terrifying ancestral shadow descends upon themselves. He must find a way out or become the next homeless person before the festival day of "Hundred Ghosts Night Parade" comes.
