When a San Francisco detective goes hunting for the cruel Asian crime figure who killed his partner, he finds himself thrown into the center of a violent plot to steal a terrorist weapon. Ty Nelson is a detective haunted by the violent death of his partner at the hands of Choy Muk, the leader of the Triad Dragons-- a violent, fanatical Asian gang operating in San Francisco. Nelson finds a mysterious clue after ending a heart-pounding chase through Chinatown alleys with the near-capture of a deadly, though beautiful Lieutenant of Choy's. But his captain has had enough of Nelson's single-minded obsession with Choy, and puts the haggard detective on leave. Nelson refuses to give up. Following a hunch, he finds himself in the center of a furious firefight as Choy and his gang try to hi-jack a diplomatic convoy carrying a priceless art treasure that has just landed at Edwards Air Force Base, bound for Los Angeles' Getty Museum.
