This box set contains the entire Lethal Weapon series.

Lethal Weapon
The thrill-packed story of two Vietnam-vets-turned-cops who have just one other thing in common: both hate to work with partners. But their partnership becomes the key to survival when a routine murder investigation leads to all-out, take-no-prisoners, martial-arts-and-machine-guns war with an intternational heroin ring.

Lethal Weapon 2
Buddy-cops Martin Riggs and Murtaugh are back, trying to keep a key witness-and themselves-alive. And exciting it is, from its breathless opening chase through L.A. streets to its raging gun-battle finale. In between, there's a six-story plummet from a window, a booby-trapped toilet, a Houdini-like underwater escape and the incredible destruction of a chic hillside stilt house.

Lethal Weapon 3
Martin Riggs finally meets his match in the form of Lorna Cole, a beautiful but tough icewoman. Together with Roger Murtaugh, his partner, the three attempt to expose a crooked former policeman and his huge arms racket. The crooked cop (Jack Travis) thwarts them at every turn, mainly by killing anyone who is about to talk, but Murtaugh has personal problems of his own as his family are brought into the equation.

Lethal Weapon 4
Mel Gibson and Danny Glover return as buddy cops Riggs and Murtaugh, with Joe Pesci riding comedy shotgun as chatterbox Leo. Murtaugh is still the family man. Riggs is still the gonzo loose cannon and--what's this?--family man. His will he/won't he marriage to Cole (Rene Russo) is one of the new wrinkles in this powerhouse crowd-pleaser.
