NCIS Celebrates 500 Episodes with a Nostalgic and Forward-Looking Episode

The long-running CBS procedural drama, NCIS, is set to reach a significant milestone with its 500th episode airing on Tuesday, March 24, 2026. After 23 seasons, multiple spin-offs, and a staggering 3.3 trillion minutes of viewing time, the show continues to captivate audiences. The episode, titled “All Good Things,” promises a blend of nostalgia and new developments for the team.

A Trip Down Memory Lane

Executive producer Steven D. Binder, who as well wrote the script, aimed to create an episode that resonated with longtime fans. “I wanted to go back to the beginning and make sure it was filled with things about our characters that longtime fans would recognize and love,” Binder stated. He also emphasized the importance of demonstrating that the show still has plenty of compelling stories to tell and that the characters continue to evolve.

The Case: A Familiar Pattern with a Twist

The 500th episode will center around a case involving the son of a Marine who was previously aided by Gibbs. The team will reunite “off the books” to pursue justice, potentially risking their careers in the process. Binder hinted at a case that will evoke emotional responses, referencing the powerful imagery of military reunions. “There will be a nice nod to that sort of energy and our service people,” he said. The case will involve a suspect who may not be who they seem, a common trope in NCIS investigations.

Agency Jeopardy and Character Vulnerability

The episode will also continue a storyline introduced earlier in the season, exploring the possibility of agency shutdowns and their impact on the team. This storyline reflects real-world concerns about the stability of government agencies. The episode will delve into the vulnerability of Director Vance (Rocky Carroll), showcasing a side of the character rarely seen. “We get to notice Vance’s Papa Bear in a way we haven’t necessarily seen him before,” Binder explained.

Looking Ahead for McGee and Jimmy

While all characters will have their moments in the spotlight, the episode will particularly focus on McGee (Sean Murray) and Jimmy (Brian Dietzen), both of whom have been with the show since its inception. The episode will “tease their futures or sets up what their futures could be,” according to Binder. He clarified that this is not necessarily a setup for their departure, but rather an exploration of their ongoing growth and development.

A Traumatic Experience and Lasting Change

Binder described the episode as a “traumatic experience” for the team, suggesting that it will lead to lasting changes in their attitudes and approaches. The case will draw upon elements from the show’s early seasons, creating a sense of continuity and connection to its roots. The episode will also feature Easter eggs and nods to past characters, including subtle references to Gibbs (Mark Harmon) and other fan favorites.

Mark Harmon’s Return and Flashbacks

Fans can expect to see glimpses of past characters through flashbacks, though there will be no major surprise appearances from former actors. Mark Harmon is set to reprise his role as Leroy Jethro Gibbs in a crossover event with NCIS: Origins on November 11, 2025, marking his first appearance in four years. According to co-showrunners David J. North and Gina Lucita Monreal, Gibbs “is no longer alone.” Good Housekeeping

The episode is a testament to the show’s enduring appeal and its ability to connect with audiences on a deep emotional level.
