A group of enthusiastic young doctors and prospective doctors formed a medical team and rushed to a village where the epidemic was spreading late at night. The young people settled in an old castle in the area, but what they didn't expect was that there was something more terrible than the plague here - rumors. There is a legend about ghosts haunting here. It is said that a black ghost often appears in the middle of the night, eating human flesh and drinking human blood. Of course, these young people will not take this nonsense to heart, especially the psychologist Jiang Hongwu (played by Nie Yuan), who believes that ghosts and gods are all psychological fantasies of human beings. However, the villagers fell one by one, and even some of these doctors really saw the "ghost". Is there really a man-eating ghost wandering in the village?
