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.

While Pride remains on probation after his rogue takedown of the corrupt Mayor Hamilton, his team is closely monitored by a strict supervisor; the team must secretly investigate after the FBI takes the lead on a case involving stolen nuclear waste.

An erratic whistleblower who calls Pride her mentor kidnaps him to help her locate a serial killer targeting young women in the Gulf of Mexico.

The team joins forces with FBI Director Isler after a Russian operative with intelligence on sleeper agents disappears; Tammy partners with former sleeper agent Eva Azarova to assist in the disappearance.

The team investigates the copycat murder of an unsolved case from 150 years ago that spawned a legendary ghost story; Gregorio is spooked when the case is connected to a recent séance and a local medium.
