Zhuang Tian (Yuen Wah) and Dong Zhaokuang (Zhang Guoqiang) were once the most famous demon catchers in the industry. However, a great social change in the late Qing Dynasty and early Republic of China turned demon catchers into charlatans who promoted feudal superstition. In desperation, the two had to go to Guangzhou, where they found a job as police officers. Although he is no longer a demon catcher, Dong Zhaokuang still can't forget his former glory. He met the businessman A Tang (Ren Shiguan). A Tang is a businessman who runs a legitimate business on the surface, but in fact he is engaged in drug trafficking. Dong Zhaokuang believed his sweet talk and began to use zombies to help him transport drugs. Dong Zhaokuang's apprentice Xiaodong (Chen Xiaodong) fell in love with A Tang's daughter Cuiling (Tan Xiaohuan), but Dong Zhaokuang had already started to have the idea of Cuiling.
