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.

The team searches for a former Irish Republican Army bomb maker who was smuggled into the city; they are joined by agent Hannah Khoury, Pride's replacement during his medical leave; Pride considers a new position within the agency.

Unable to trust anyone in New Orleans, the NCIS team calls in FBI Assistant Director Isler to help expose and stop Mayor Hamilton's sinister scheme.

The team investigates the murder of a Navy captain who was searching for a priceless 200-year-old fleur-de-lis during the annual Louisiana Pirate Festival.

Pride, Sebastian and Tammy travel to South America after Pride is personally requested by a former colleague to assist with a classified operation that has been compromised.
