One of the longest-running series of all time, the crime drama is back on with NCIS Season 23. First premiering in 2003, we are introduced to Special Agents of the Major Case Response Team from the Naval Criminal Investigative Service. Leading the NCIS team was Special Agent Leroy Jethro Gibbs, the original protagonist of the series from season 1 until his departure in season 19.

What is the plot of NCIS?
The NCIS investigates criminal activities with Navy and Marine Corps ties, crimes of which range from murder and espionage to terrorism. Throughout the years, the show’s main cast members have changed, with David McCallum’s Dr. Donald “Ducky” Mallard and Sean Murray’s Timothy McGee being the only original cast members of the series. McCallum unfortunately passed away on 25 September 2023.
Now in its twenty-third season, the new series picks up where the cliffhanger NCIS Season 22 finale left off: Laroche is a double agent for the Department of Defense, Carla Marino is the leader of the Nexus cartel and her deliberate revenge as she blames Parker for her son’s death.
The events of the season 22 finale will heavily influence season 23, as Parker stops at nothing to pursue Carla Marino for the shocking murder of his father. The team’s limits are pushed further than ever, testing loyalties and putting the careers they’ve spent a lifetime protecting on the line.
NCIS was created by Donald P. Bellisario and Don McGill. Bellisario is also executive producer alongside Steven D. Binder, Frank Cardea, Chas. Floyd Johnson, Mark Harmon, and Mark Horowitz.

He is joined by Diona Reasonover as NCIS Forensic Specialist Kasie Hines, Katrina Law as NCIS Special Agent Jessica Knight, Rocky Carroll as NCIS Director Leon Vance, Brian Dietzen as Dr. Jimmy Palmer, Wilmer Valderrama as NCIS Special Agent Nicholas Torres.
