Story in 60 Seconds

The short version

Lethal Weapon pairs Martin Riggs, a suicidal former special forces detective grieving his wife, with Roger Murtaugh, a veteran police officer trying to reach retirement safely. Their case begins with a young woman's death and expands into a drug-smuggling operation tied to ex-military criminals. Murtaugh distrusts Riggs's recklessness, while Riggs is pulled toward Murtaugh's family and the stability it represents. As the criminals target Murtaugh's daughter Rianne, the partnership becomes personal. Riggs and Murtaugh rescue her, expose the network, and defeat Joshua, with Riggs choosing connection over self-destruction.

The ending matters because Riggs does not simply win a fight; he accepts a reason to keep living. Giving Murtaugh the bullet he had saved for suicide is the emotional resolution of the buddy-cop story. The case brings the partners together, but the deeper shift is Riggs moving from death wish to chosen family. Murtaugh gains a dangerous partner, and Riggs gains a home to return to.
