This film tells the story of a bizarre tragedy in which Yao Xiu, a daughter of the Yao family, was bewitched by a white demon and turned into a demon in a mountain village called Gushan Village during the Republic of China. Many years later, Yao Xiu, under the pseudonym Lu Xiaoan, returned to Gushan Village to find out why her family was killed. In the end, she used a clever trick to find the real culprit and broke the illusion that the white demon could possess and control people. She revealed that all feudal superstitions were rumors and legends, and advocated breaking superstitions, advocating science, establishing a correct world view, and firmly believing in materialistic ideas.
