The game is set around the transfer of sovereignty over Hong Kong in 1997. People from the Chinese Mainland started immigrating to Hong Kong and greatly increased the crime rate. As a countermeasure, Chin (Jackie Chan in his Wheels on Meals appearance), an unspecified relative of Bruce Lee and a heroin addict, was hired by the Hong Kong government (represented by Chris Patten) to wipe out all 1.2 billion people in China. But meanwhile, in China, research was underway to bring the dead Tong Shau Ping (Deng Xiaoping) back to life as the "ultimate weapon".
