Lethal Weapon

In the combustible action franchise's final installment, maverick detectives Martin Riggs and Roger Murtaugh square off against Asian mobster Wah Sing Ku, who's up to his neck in slave trading and counterfeit currency. With help from gumshoe Leo Getz and smart-aleck rookie cop Lee Butters, Riggs and Murtaugh aim to take down Ku and his gang.

Archetypal buddy cops Riggs and Murtaugh are back for another round of high-stakes action, this time setting their collective sights on bringing down a former Los Angeles police lieutenant turned black market weapons dealer. Lorna Cole joins as the beautiful yet hardnosed internal affairs sergeant who catches Riggs's eye.

Riggs and Murtaugh are trying to take down some drug dealers but the they turn out to be not run of the mill drug dealers; they have automatic weapons and helicopters. Eventually they grab one of their vehicles and find a million dollars worth of gold coins or Krugerrands in the trunk. Later Murtaugh is threatened by the men they're pursuing. That's when the Captain reassigns them to protect a man named Leo Getz who is suppose to testify in a big case. When they get to where Leo is, someone tries to kill him and that's when they learn he laundered half a billion dollars worth of drug money. He then takes them to a place he once went to and that's when the people there start shooting at them. Later when they come back with back up they learn that the men work for the South African consulate and have diplomatic immunity. They deduce that they are the ones they were looking for, but because of they have diplomatic immunity they can't do anything.

Martin Riggs is an L.A. cop with suicidal tendencies and Roger Murtaugh is the unlucky police officer with whom Riggs is assigned. Together they uncover a huge drug-smuggling operation, and as their success rate grows so does their friendship.
