NCIS Season 21 is set to premiere in 2024, as the production has been delayed due to the writers and actors strikes. The last episode of Season 20 ended with a cliffhanger for Nick Torres, played by Wilmer Valderrama, as he confronts a mysterious man from his past. It is unclear if Torres will follow Gibbs' path and cross moral and ethical lines in the new season. As for the cast, there is no indication of any main players leaving, so it is safe to assume they will all return. Mark Harmon, who played Leroy Jethro Gibbs, has already left the show during Season 19, but the possibility of past fan favorites returning is still uncertain. NCIS can be streamed on Paramount+ and Netflix. There will also be re-airings of episodes on CBS this fall.
