Few shows have reached the height that NCIS has. The popular crime drama on CBS has aired 18 seasons and has spawned multiple spinoffs, including NCIS: Los Angeles, NCIS: New Orleans and a brand new spinoff, NCIS: Hawai’i. But the original NCIS just keeps rolling along, as it gets ready for its 19th season.

NCIS, which debuted on CBS in 2003, was created by Donald P. Bellisario and Don McGill, both of whom are still writing for the show. With these veterans pulling the strings behind the scenes, what can we expect from this latest season of NCIS? Read on to find out everything we know about NCIS season 19.

What is the plot of ‘NCIS’?

NCIS is about the cases handled by the Naval Criminal Investigative Service agency from their Washington, D.C., office. The team is led by Special Agent Leroy Jethro Gibbs as they work each week to solve a specific case.

To start season 19, the team will be dealing with an explosive finale from season 18. SPOILER ALERT if you are not caught up on the latest episodes of NCIS. In the NCIS season 18 finale Ellie Bishop decided to go undercover, with a sad goodbye to Nick Torres; elsewhere, Gibbs believes that a serial killer that he has been tracking is following him. He persists with the investigation though, travelling by boat to try and search for evidence when it suddenly blows up. Gibbs body floats to the surface and appears to be lifeless, however, he eventually swims away.

The first episode of season 19 will deal with the aftermath of the explosion, as Gibbs is missing. It’s possible that Gibbs may be missing for multiple episodes this season, as reports have indicated that CBS is willing to work around star Mark Harmon’s schedule.

Who is in the ‘NCIS’ cast?

Mark Harmon has been the lead of the series from the start, though we have a SPOILER ALERT for anyone not caught up on the season thus far.

It appears that after solving the case of the serial killer, Harmon's Jethro Gibbs has decided to stay in Alaska, where he has been able to find peace for the first time in a long time. This marks the end of an 18 year and change run for Harmon on the show. CBS and the NCIS creatives were mum on whether he may appear in guest roles somewhere down the line, but for the moment Harmon's time on NCIS is over (in front of the camera, he is still an executive producer).

Here is the rest of the NCIS team for season 19:

  • Sean Murray - Timothy McGee
  • Wilmer Valderrama - Nick Torres 
  • Brian Dietzen - Jimmy Palmer 
  • Diona Reasonover - Kasie Hines 
  • Rocky Carroll - Leon Vance 
  • David McCallum - Donald Mallard 

New to the NCIS cast this year will be Gary Cole, Allie Davis, Pam Dawber and Katrina Law. 

When does ‘NCIS’ air?

NCIS is moving from its Tuesday airday that it has held for 18 seasons, now instead airing on Mondays at 9 p.m., serving as the lead-in to its spinoff show, NCIS: Hawai’i.

For anyone missing the NCIS in its usual time, it can watch the latest episode on the CBS website or Paramount Plus the day after it airs.

NCIS can be watched live on your local CBS station.
