A cop and his team of comrades go undercover in one of China's most ruthless underworld organization to stop a gang leader, only to put themselves in great danger after being exposed one by one.
Dragon has been an infiltrator in Hung's Hong Kong triad gang for many year. After a failure of a recent negotiation by Dragon with the other three local triad gangs on behalf of Hung makes the latter suspicious of Dragon's identity. Hung sets to wipe out every undercover cop in his gang and as a result many cops are caught and wiped out. Sening the danger, Dragon requests to put an end to his undercover career from his captain, Cheung. However, Cheung sends Dragon to Mainland China to infiltrate a business of "Special Identity" trading intead. The business is run by Hung's best protégé, Sunny, who was Dragon's previous buddy in the gang. Cheung promises to reintate Dragon's police identity in conclusion of the mission once Sunny's business breaks down. Dragon agrees, and joining him are local police officer Lei Peng and Fang Jing from the Mainland Chinese police force. But before they can get to Sunny, the latter suddenly vanishes leaving Dragon exposed and in great danger.
