'NCIS' Season 23 premiered in October 2025 and is set to end its 20-episode run a month from now in mid-May. The latest season has already seen the death of the beloved NCIS Director Leon Vance (Rocky Carroll) in the show's 500th episode, which aired last month. So, we wonder if the series will go out with a bang and deliver another shocking twist to close out Season 23. The police procedural drama recently aired episode #16, titled 'S.O.S.,' on Tuesday. It centered on the Navy lieutenant Rebecca Lee (Yael Grobglas), who went missing a year ago after her plane disappeared. After she returned, the team set out to learn what she had been up to over the past year. There are three more episodes left before the finale, which airs on May 12.

CBS recently released the official synopsis for the finale, which reads "One year after a deadly coffee shop bombing, a new explosion proves the attack wasn't the work of a lone wolf – a case that forces the team to confront legacy and loyalty." The closing chapter of Season 23 is titled 'Sons and Daughters.' It is written by Christopher J. Waild and directed by Jose Clemente Hernandez. The network also shared a preview image of the finale, showing the team sifting through the carnage left by the bomb blast.

The NCIS team will be revisiting a year-old case that will come back in the spotlight due to another similar attack. The synopsis also mentions that the team will be pulled into another high-stakes chase, but this time it will be personal, revolving around the team's 'legacy and loyalty.' The legacy aspect hints at a possible connection to Director Vance, who led his team heroically for decades from Season 5 (2007) until Season 23 (2026). Perhaps the late director's handling of the case led to problems that the team must address to protect his legacy. As the team goes to work tracking down the culprits, they will likely uncover a larger conspiracy with potential ties to team members.
