There is a strange secret in Shi Village. The villagers are all wild boars wearing human skin. They eat human flesh to maintain their skin and change their skin every nine years to survive. Xiaodong has kept in mind his mother's instructions since he was a child: "Never take off human skin or eat human flesh." However, when a hunter comes to the village to investigate the disappearance, he is forced to be involved in the conspiracy. He accidentally uncovered the truth that the "Holy Land" was actually a slaughterhouse, and the mother was used as an experimental fertility tool. With the village chief lurking and the tribesmen rioting, a revenge plan quietly unfolded. But when they broke through the factory, they fell into a deeper scam - all of this was an experiment by biologists, and Xiaodong was the "perfect new product" that was about to be put on the shelves.
