Riggs (Mel Gibson) is no ordinary cop. He's a Mad Max gone maniacal, a man whose killing expertise and suicidal recklessness make him a Lethal Weapon to anyone he works against, or with. Murtaugh (Danny Glover) is an easygoing homicide detective with a loving family, and a pension he doesn't want to lose. Lethal Weapon is the thrill-packed story of two Vietnam-vets-turned-cops who have just one other thing in common: both hate to work with partners.
