Federal Marshal John Kruger (Arnold Schwarzenegger) is assigned to look after people as part of the Federal Witness Protection System. His latest charge is Lee Cullen (Vanessa L. Williams), a key witness in a case against her employers, the Cyrez Corporation, who are secretly selling their hi-tech weapons to the Russian Mafia. Her safe passage to the courtroom is endangered by corruption within the ranks of Kruger's bosses, which leads to him being framed and thrown off the force.

Box set containing all four films from the popular 'Lethal Weapon' series. In 'Lethal Weapon' (1987), Roger Murtaugh (Danny Glover) is a family man cop who is about to turn fifty. Cautious by nature, he is less than happy to be paired with Martin Riggs (Mel Gibson) when he is assigned to investigate Californian drug baron 'The General' (Mitchell Ryan). Following the death of his wife, Riggs has become a manic loner who no longer cares whether he lives or dies - an approach which causes more than a few problems as he and Murtaugh attempt to bring the General to justice. In 'Lethal Weapon 2' (1989), Riggs (Gibson) and his partner Murtaugh (Glover) once again tackle the evils of drug smuggling, this time coming up against a South African syndicate whose kingpins are protected by diplomatic immunity. In 'Lethal Weapon 3' (1992), Detectives Murtaugh (Glover) and Riggs (Gibson) are both demoted after triggering a car bomb in a multi-storey car park, but they are soon reinstated after uncovering a network - run by an ex-cop - which is smuggling weapons out of a police ammunition dump. Finally, in 'Lethal Weapon 4' (1998), mismatched cops Riggs (Gibson) and Murtaugh (Glover) team up for a fourth time to foil an immigrant smuggling racket, run by a ruthless Asian Triad leader (Jet Li). Joe Pesci also returns as Leo Getz, the cops' cowardly informant whilst Rene Russo leavens the boys with toys atmosphere as risk-taking detective Lorna Cole.
