Set against the breathtaking backdrop of the Hawaiian Islands, this action-packed spin-off follows the elite team of special agents at the Naval Criminal Investigative Service's Pearl Harbor field office. Led by the sharp and resourceful Special Agent in Charge Jane Tennant, portrayed by Vanessa Lachey, the team tackles high-stakes crimes involving military personnel, national security threats, and complex local mysteries. Tennant, a single mother balancing her demanding career with raising two children, commands a diverse group including the steadfast second-in-command Alex Tarrant as Kai Holman, the tech-savvy Lucy Tara played by Yasmine Al-Bustami, and the formidable Jason Antoon as Ernie Malik, the team's brilliant cyber intelligence specialist. As they navigate cases ranging from terrorism to espionage, the agents confront the unique challenges of island life, where paradise often conceals danger. With a tone that blends the procedural grit of the original NCIS franchise with the sun-drenched allure of Hawaii, the series delivers compelling character dynamics, personal sacrifices, and a deep sense of ohana—family—that binds the team together in their relentless pursuit of justice.
