Buttoned-down veteran 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.

When average, law-abiding citizens suddenly turn to a life of hedonistic behavior and violent crime, Detective Tom Beck is tasked with helping young FBI agent Lloyd Gallagher determine the cause.
