Legendary NCIS Agent Sam Hanna returns to his hometown of New York City to their field office and helps lead a new team as they are tasked with high-stakes missions to defend one of the most vital cities and ports in the world.

The team is called in when a Navy admiral sacrifices himself to save the life of an AI tech mogul after an assassination attempt by an unstable shooter.

When Sam Hanna's friend and Navy reservist Jack Halloway is found dead, he requests permission from Assistant Special Agent-in-Charge Robyn Wells to investigate his friend's death.
