Agent Dwayne "King" Pride has a team out of New Orleans' NCIS field office that is investigating crimes that affect military personnel. He's a local guy with a drive to do the right thing and leads agents Christopher LaSalle -- who plays almost as hard as he works -- and former ATF agent Sonja Percy -- who finds being a part of a team an adjustment after years of working undercover assignments on her own. Eccentric coroner Dr. Loretta Wade supports them on cases. Together, they delve into the dark side of the colorful city that's a magnet for servicemen on leave.

A petty officer is murdered while in town to help a refugee family; Wade works on the special election campaign for Mayor Zahra Taylor that takes place during Mardi Gras.

FBI Special Agent Raymond Isler asks Pride for help with an off-the-books opioids theft investigation he is personally invested in; Percy works undercover as a getaway driver, with Isler as the muscle for a job tied to the case.

A congressional aide disappears after a hit man saves her from two men posing as NCIS agents; LaSalle struggles with life-altering decisions regarding his brother's future.

Pride and the team are on the hunt for a kidnapped 14-year-old and discover that her father, who will soon have custody of her, is a radical survivalist living off the grid.
