The NCIS team investigates the murder of a petty officer who was in town to help a refugee family being recruited by terrorists. Also, Wade works on the special election campaign for Mayor Zahra Taylor that takes place during Mardi Gras.
The local NCIS field office investigates criminal cases affecting military personnel in the Big Easy, a city known for its music, entertainment and decadence. Leading the team is Special Agent Dwayne Pride, aka 'King', a native of NOLA who is driven by his need to do what is right. Working with Pride is Special Agent Christopher LaSalle, who plays hard but works harder; and Special Agent Meredith 'Merri' Brody, a charismatic and tough interrogator who transferred from the Great Lakes office in search of a fresh start. Supporting them is coroner Dr. Loretta Wade, who is as eccentric as she is smart. This colorful city that harbors a dark side is a magnet for service personnel on leave, and when over-indulgence is followed by trouble, Pride's team is at its best.
