Hitman John Lee owes a debt to Mr. Wei, L.A.'s Chinatown drug-lord. When a cop kills Wei's adult son during a drug bust, Wei instructs Lee to kill the cop's seven-year old son while father and son are at play. Lee can't pull the trigger, and he knows Wei will punish him by going after Lee's mother and sister in Shanghai. To reach them fast, Lee needs a forged passport. He seeks out Meg Coburn, a forger. But Wei's men are already on Lee's trail, disrupting his visit to her. Lee and Coburn must fight them off, evade the cops, face replacement killers imported to shoot the cop's son, confront Wei, and get Lee onto a plane to China, passport in hand.
