NCIS Season 23: Legacy of the Compass (2026)
Starring Sean Murray, Wilmer Valderrama, Katrina Law, Gary Cole, and Brian Dietzen
The world’s most elite naval investigative team returns to the small screen, confronting a formidable threat that strikes at the very heart of their storied history. In the milestone twenty-third season of NCIS, Special Agent Timothy McGee (Sean Murray) uncovers a long-hidden, highly encrypted file left behind by the legendary Leroy Jethro Gibbs. This digital ghost points to a dormant cold case that weaves together decades of high-level corruption and systemic rot within the Department of Defense. As the Major Case Response Team begins to peel back the layers of this mystery, they realize they aren’t merely solving a forgotten crime; they are exposing a deep-state conspiracy that has been waiting in the shadows for the perfect moment to strike.

Supervisory Special Agent Alden Parker (Gary Cole) must navigate the team through a treacherous gauntlet of intense political pressure and sophisticated high-tech sabotage designed to derail the investigation. Meanwhile, Nick Torres (Wilmer Valderrama) and Jessica Knight (Katrina Law) go undercover in the field to track an infamous black-market arms dealer who has resurfaced in the heart of Washington D.C. with a dangerous new agenda. The stakes escalate to a personal breaking point when the life of a former team member is placed directly in the crosshairs, forcing the agents to decide exactly how much they are willing to sacrifice to protect the Legacy of the Compass.

The new season maintains the franchise’s signature blend of intricate forensic mystery, high-octane action, and the deep-rooted camaraderie that has captivated global audiences for over two decades. In an era defined by evolving digital warfare and complex geopolitical shifts, the team proves that no matter how much technology changes, the fundamental pursuit of truth and justice remains constant.
