Editing Lethal Weapon 4 (section)

==Plot==
Lorna Cole is pregnant with [[Los Angeles Police Department|LAPD]] Sergeant Martin Riggs's baby; they are not married, but both are thinking about it. LAPD Sergeant Roger Murtaugh's daughter Rianne is also pregnant but won't reveal who the father is.

The officers and Leo Getz come upon a [[Han Chinese|Chinese]] immigrant smuggling ring after running an oceangoing vessel aground, though the boat's captain escapes. Murtaugh finds the Hong family hiding from US Immigration officers to avoid deportation. Murtaugh offers them shelter in his home, and their families, along with Riggs and Cole, bond. Grandfather Hong is looking for his uncle, a skilled engraver, who had paid for their passage to the United States. Riggs discovers through Lorna that the father of Rianne's unborn child is Detective Lee Butters. The family is hiding this from Murtaugh, who would not approve of his daughter being with a police officer.

Continued investigation of the smuggling ring leads the officers to "Uncle" Benny Chan, a crime boss operating from a [[Chinatown]] restaurant. There, they are introduced to high-ranking [[Triad (underground society)|Triad]] negotiator Wah Sing Ku. Chan forces them out of his restaurant when the officers show no probable cause. Riggs pulls the fire alarm so that the sprinklers can go off, forcing all the restaurant customers to flee.  Outside, Riggs spots the ship captain and tries to give chase but fails to capture him. Ku later intercepts the captain and kills him as punishment for attracting the police's attention.

Hong manages to contact his uncle, but this leads the Triads to Murtaugh's house. Ku and the Triad thugs kidnap the Hongs, tie up Murtaugh, his family, Riggs, and Cole and set the house ablaze. Ping, Hong's grandson, has evaded capture and helps to free the others in time. Though Riggs and Murtaugh chase down and kill Triad members, Ku escapes. Ku brings Mr. Hong to his uncle at a warehouse, where he has been engraving plates for a counterfeiting operation for Ku and Chan in exchange for transit for his family. Ku kills Hong in front of his uncle to assure his continued work.

With Getz serving as a distraction, the officers confront Chan at his dentist's office to interrogate him with [[laughing gas]] for more information but cannot get any leads, and during which Riggs and Butters accidentally reveal the family secret to Murtaugh. Later, as they discuss what they know with Detective Ng, who has worked on cases involving the Chinese government before, Ng recognizes that Ku must be trying to negotiate with a corrupt Chinese general for the release of the Four Fathers, high-ranking Triad members that include Ku's brother. New information leads them to the abandoned warehouse where they find the bodies of Hong, his uncle, and Chan, the latter two killed by Ku after they served their usefulness. Knowing that Ku plans to use counterfeit money, the police intercept the exchange between Ku and the general, telling the general that the money is fake. The enraged general executes most of the Four Fathers before being killed by the Triads. A firefight breaks out between the Triad, the general's private army, and the police; most of the Triad and army die, and Butters is wounded shielding Murtaugh. Ku attempts to escape with his brother, who is killed by Murtaugh. Riggs and Murtaugh pursue Ku to a pier and engage him in a fistfight. Murtaugh impales Ku through the stomach with a rebar before being knocked out by Ku. The pier then collapses and sends Riggs and Ku into the water. Riggs finds an assault rifle and kills Ku, while Murtaugh recovers in time to rescue Riggs from a piece of concrete that had pinned him underwater.

Riggs and Getz later discover that Lorna is about to give birth and race to the hospital, where Riggs and Lorna are ceremonially married by a [[rabbi]] just before she enters labor. Their son and Rianne's daughter are born, and Murtaugh accepts Butters as his son-in-law. Hong's family is granted [[right of asylum|asylum]].
