The series stars Damon Wayans as Roger Murtaugh, a senior Los Angeles Police Department detective who returns to the force, after recovering from a heart attack, and is partnered with Texas transfer Martin Riggs, played by Clayne Crawford.
Later on, a suspect tells Riggs that Murtaugh was the target of the shootout and Trish's senior partner in her workplace has been laundering money for the AFT.
However, as Riggs makes one last visit to his wife's grave, Garrett shows up and fatally shoots him in the chest.
Following a harrowing experience in Afghanistan, a war veteran Wesley Cole (Seann William Scott) finds himself working for the LAPD issuing parking tickets as a way to get closer to his daughter and estranged ex-wife.
A chance encounter with Chechnyan mobsters pairs Cole with Murtaugh, who is still reeling from Riggs's death and is considering retirement.
