Martin Riggs and Roger Murtaugh, each now feeling too old to be doing what theyre doing, try to stop the Chinese Triads from doing their illegal business in the U.S. Uncle Benny, Chinatowns mob boss, has imported Chinese slaves to pay for an artist to create counterfeit Chinese currency which the Triads (led by Jet Li) will use to buy the Four Fathers (heads of the Triads) back from the Chinese military. Chris Rock joins the team as a new cop and Riannes husband. Lorna is pregnant and considers marriage with Riggs, and Leo Getz is back, now as a private investigator.
