NYPD Lieutenant Nick Chen is head of the Asian Gang Unit. His job is to keep the peace in
Chinatown from a turf war that has broken out between the Tung Fung Benevolent Association
tong and the Fukienese Dragons street gang. The problem is complicated by the fact that he is also an informant for the Tongs under Uncle Benny Wong and his lieutenant Henry Lee. After a bombing in Chinatown, Chen is reluctantly teamed up with Danny Wallace, who is unaware of Chen's corruption. Danny was also secretly tasked by Internal Affairs to monitor Chen. Danny lied to Chen and the Asian Gang Unit by claiming that he had taken the job to gain his detective shield quickly. During a police raid on a Fukienese whorehouse, Chen saves Wallace's life. Wallace, knowing that his life is now in Chen's hands, initiates a bust on a drug operation, not knowing that an undercover
FBI agent is involved. After being berated by the FBI for interfering with an ongoing investigation, Wallace is introduced to Lee. Lee discusses the potential value of having another cop in the AGU on the Tong payroll, which Uncle Benny allows. Benny is able to lure Wallace into working for him by tipping him off to an underground prostitution ring. Wallace is given a commendation for valor, but Chen now suspects him working for the Tongs. Wallace and Chen inadvertently cross paths, throwing their initial trust for each other out the window and putting Lee's intentions into question. Chen hates the Fukienese, but neither he nor Danny knows that Lee is forming a partnership with their leader Bobby Vu. Both Lee and Vu know that there is an FBI agent undercover in their drug operation and decide to kill him. While monitoring a drug operation, Wallace and Chen witness a violent confrontation with a Tong hit squad that leads to Chen getting berated for botching the FBI investigation. After the incident, Wallace and Chen swear not to talk to the FBI without talking to each other first. The FBI finds out Wallace's real reason for joining the AGU and threatens to expose him unless he is willing to spy on Chen. When Jack, one of Chen's informants, witnesses Vu's assassination of Uncle Benny, Chen alerts the DA, who intends to indict the Tongs under
RICO. The DA, the FBI, and both Wallace and Chen decide that they want to catch Vu in the act and decide to hold off on the arrests. Lee chooses to alert Chen of Wallace's real identity and job. During the nighttime operation, Chen draws his gun on Wallace in anger. Wallace reasons with Chen and the two fight the Dragons, killing most of them. Chen pushes Wallace out of the way and is fatally shot by Vu. Wallace then shoots Vu. While at the hospital, Wallace refuses to withdraw his original statement that Chen died a good cop. Later, Wallace leads the arrest of Lee. Chen is then given a hero's funeral with Wallace in the procession. ==Cast==
