The era of standard investigations is over; the age of sovereign shadows has begun. NCIS: Sea of Secrets reunites the legendary team for an event that transcends military procedure, evolving into a high-stakes, neon-noir geopolitical thriller. When the USS Erebus—a nuclear-class submarine decommissioned and thought lost to a deep-sea trench thirty years ago—suddenly breaches the surface off the coast of the Atlantic, it carries no living pulse. Instead, it holds a ghost crew, a payload of encrypted biological data, and a single, handwritten message addressed to one man: Gibbs.

Mark Harmon returns as Leroy Jethro Gibbs, emerging from the Alaskan wilderness with a weathered, obsidian-noir intensity. No longer just a retired agent, he is the Strategic Ghost of the agency. Dressed in lethal, high-fashion tactical gear that blends rugged survivalism with the cold authority of a commander, Gibbs is the only one who can decipher the “Old Rules” hidden within this new-world conspiracy. He moves with a surgical precision that proves the legend hasn’t just survived—he has evolved.

Sean Murray reprises his role as Timothy McGee, now the Executive Director of Cyber-Tactical Operations. McGee has rũ bỏ hoàn toàn the “Probie” image, standing as a lethal strategist in sharp, tech-integrated tailoring. He must now balance Gibbs’ gut-driven instincts with a sophisticated arsenal of AI-driven forensic warfare. Beside them, Nick Torres (Wilmer Valderrama) provides the raw, lethal muscle of the unit. Dressed in sleek, obsidian tactical armor, Torres leads high-octane night raids on deep-sea oil rigs, turning the ocean into his personal hunting ground.

The threat is The Obsidian Lattice—a shadow organization embedded within the highest echelons of the government. They have weaponized the submarine’s secrets to trigger a naval war that would redraft global borders. As Jimmy Palmer (Brian Dietzen) utilizes high-level molecular forensics to uncover a betrayal reaching back decades, the team realizes the enemy is already inside the house.
