Plot Summary

In Lethal Weapon 2, veteran detectives Martin Riggs (Mel Gibson) and Roger Murtaugh (Danny Glover) are assigned to protect a key witness—an accountant whose testimony could expose a massive money-laundering operation involving hundreds of millions of dollars.

As the investigation deepens, Riggs and Murtaugh uncover a sophisticated criminal network with international ties, revealing that the financial crimes are only the surface of a far-reaching drug cartel operation. What initially appears to be a routine protection detail quickly spirals into a deadly confrontation with powerful enemies who operate above the law.

Determined to silence the detectives, the cartel exploits diplomatic immunity, political leverage, and ruthless violence. Forced to fight both the criminals and a corrupt system shielding them, Riggs and Murtaugh push their partnership to the limit, balancing explosive action with dark humor as they pursue justice at any cost.
