Veteran buttoned-down LAPD detective Roger Murtaugh is partnered with unhinged cop Martin Riggs, who — distraught after his wife’s death — has a death wish and takes unnecessary risks with criminals at every turn. The odd couple embark on their first homicide investigation as partners, involving a young woman known to Murtaugh with ties to a drug and prostitution ring.

Archetypal buddy cops Riggs and Murtaugh are back for another round of high-stakes action, this time setting their collective sights on bringing down a former Los Angeles police lieutenant turned black market weapons dealer. Lorna Cole joins as the beautiful yet hardnosed internal affairs sergeant who catches Riggs’s eye.
