In the late Qing Dynasty and early Republic of China, the people of Xiangcheng, Nanguo, were ignorant and evil forces were rampant. The head of the police, Kong Xueli, and the coroner, Fang Dong, were not afraid of evil. They used their modern scientific knowledge to fight against the dark forces that pretended to be ghosts and exposed their ugly faces. The common people also gradually awakened in the confrontation between the forces of good and evil. Although Kong Xueli and Fang Dong have different personalities, they both have a sincere heart of justice. In the process of cracking the secrets of the rivers and lakes and sweeping away feudal superstitions, they became a pair of good brothers who shared life and death. During this period, Kong Xueli and the restaurant proprietress fell in love at first sight, but they almost broke up because of the dark forces. In the end, the proprietress broke through the shackles of superstition, and the lovers finally got married.
