Criminal policeman Li Guoqiang (played by Shawn Yue) shot and killed the murderer Chen Fulai, and was shot several times. He rested in the hospital for 49 days, but just after being discharged, he was informed that his position had been transferred to the Miscellaneous Department, just because there were some supernatural phenomena in his testimony that could not be explained by science. Li Guoqiang, who came to the Miscellaneous Department, met Inspector Huang (played by Ekin Cheng). This slightly fat and alcoholic middle-aged man told him that unlike other departments, the Miscellaneous Department specializes in dealing with so-called "supernatural events", but if you want to survive here, you must firmly believe in one thing, that is, the first commandment: "There are no ghosts in this world!" But there are really ghosts in this world. Several strange suicide cases that have occurred in recent months have attracted Li Guoqiang's attention. Through investigation, he found that this was the soul of Chen Fulai who had not changed his murderous intention. He could attach himself to anyone by touching them, and then manipulate their bodies to do whatever he wanted. In order to subdue the murderer, Li SIR and Huang SIR joined forces and launched a thrilling pursuit. However, at this moment, Li Guoqiang gradually couldn't tell whether Inspector Huang, who had always been helping him, was an enemy or a friend.
