Description：There is a police station in Hong Kong, which was a military camp when the Japanese invaded Hong Kong 30 years ago. Because of the defeat, the Japanese officers committed suicide in the police station. It is said that their ghosts are still lingering in the police station and will appear on the day of the Menglan Festival. Jin Maji (Jacky Cheung) and Meng Chao (Hui Guanying) are both police officers in this police station, but they have never believed in the horror legends in the police station. It was not until the day of the Menglan Festival that they witnessed the fugitive She Zai Ming (Lou Nanguang) turned into ashes when he encountered the sun. It turned out that She Zai Ming saw the ghosts of the Japanese army in the prison and turned into a zombie after being bitten. Only then did they believe that there were indeed ghosts in the police station. They reported the situation to their superiors and were about to find out the truth, but they met a woman who was suspected to have been bitten by a zombie and died. A contest between the police and the evil spirits has officially begun...
