NCIS: Sea of Secrets (2026)
Mark Harmon, Sean Murray, Brian Dietzen, Wilmer Valderrama
The horizon darkens, and the depths of the ocean conceal secrets that refuse to stay buried. After the monumental events of the series' long-running history, NCIS: Sea of Secrets brings Special Agent Leroy Jethro Gibbs (Mark Harmon) out of the shadows for one last, high-stakes mission. When a decommissioned Navy submarine resurfaces with a ghost crew and a cryptic message, the Major Case Response Team is thrust into a global conspiracy that could ignite a naval war.
Sean Murray reprises his role as Timothy McGee, now a seasoned leader who must balance Gibbs' old-school instincts with modern cyber-warfare tactics. As they dig deeper, the team uncovers that the case is not just about military secrets—it's about a betrayal that spans decades, reaching the very roots of NCIS itself. The team must navigate a maze of classified documents and high-stakes tension, where every wave could bring a new adversary.
With the keen medical insight of Jimmy Palmer (Brian Dietzen) and the raw field expertise of Nick Torres (Wilmer Valderrama), the MCRT races against the clock. But this time, the "Unknown Subject" isn't a person—it's a shadow organization within the government determined to keep the past buried.
NCIS: Sea of Secrets delivers the perfect mix of procedural grit, emotional reunions, and explosive maritime action. Old rules will be broken, loyalties will be tested, and as Gibbs always says: never let them see you coming. The tide is turning, and the truth is finally coming to the surface.
