The film begins with the sun setting in Tokyo. Unknown to most people, there is the demonic "Rapter World" in conflict with human world. Rapters shift their shapes and infiltrate human world. Taki (or "Leung", played by Leon Lai) is a sales of a Hong Kong import/export company, but that is only his cover. He reveals his real occupation when he hunts down a seductive spider-like rapter in Tokyo. Ken saved his life when Taki ran out of bullets. Taki belongs to the Anti-Rapter Special Police. One day he is transferred back to Hong Kong. The 1997 transfer of Hong Kong is near, Anti-Rapter Special Police Headquarter transferred many agents from Hong Kong to the United Kingdom. This is a chaotic period when Hong Kong is most vulnerable to rapters. That's why Taki is sent to Hong Kong to help.
