The three-hour crossover event kicks off Monday night with NCIS, followed by NCIS: Hawaii and NCIS: LA, and only ET exclusively premieres a sneak peek from the second hour from Hawaii.
In the clip, NCIS’ Alden Parker (Gary Cole) meets members of the Hawaii team as they go over the big case that’s brought all three teams together. As the scene plays out, it’s clear Parker isn’t used to the dynamics of the team. This is the first time all three NCIS teams, led by Vanessa Lachey, LL Cool J, Chris O’Donnell, Sean Murray and Wilmer Valderrama, will participate in one storyline on the same night. The NCIS crossover will center around a very personal, high-stakes case to take down a mysterious hitman.
According to CBS, team members from the different NCIS divisions come together in Washington, D.C., to celebrate a beloved FLETC (Federal Law Enforcement Training Center) professor who taught multiple members of each of the squads. On the eve of the celebration, the professor is found dead of an apparent suicide and his former students immediately suspect foul play. While investigating his past, they uncover a mysterious hitman and the more they dig into it, the bigger the targets on their backs become. Members of the team are suddenly kidnapped and all the agents must come together to take down the assassin and save their own.
The NCIS Crossover Fans Have Been Waiting For
If you’re an NCIS fan, buckle up — the ultimate crossover is finally happening. Special Agent Alden Parker is stepping out of D.C. and landing in sunny Hawaii to team up with the NCIS: Hawaii squad. This isn’t just a casual visit — it’s action-packed, emotionally charged, and brimming with drama.
Why This Crossover Is a Big Deal
Bridging Two NCIS Universes
Crossovers in the NCIS franchise aren’t new — but bringing Gary Cole’s Alden Parker to Hawaii’s NCIS branch, led by Vanessa Lachey’s Jane Tennant, is game-changing. It’s a meeting of minds, methods, and maybe a few culture clashes along the way.
Fan-Favorite Characters in One Episode
Seeing characters like Lucy Tara, Kai Holman, and Ernie Malik interact with the gruff yet sharp Alden Parker? It’s the kind of content fans live for — layered, complex character dynamics mixed with signature NCIS suspense.
The Premise — What Brings Parker to Hawaii?
A Case Too Big for One Team
In the sneak peek, Parker is brought into the fold due to an investigation with ties to both mainland and island crime rings. With jurisdiction overlapping and the stakes rising, Parker is sent to assist — but also to keep tabs.
Inter-Agency Tension? You Bet.
Expect friction. Tennant and her team run things differently. Parker’s by-the-book style might rub some the wrong way. And yet, their shared mission pulls them together in unexpected ways.
Who’s Who in This Crossover Event
Alden Parker (Gary Cole)
D.C.’s NCIS leader, pragmatic, old-school, and fiercely loyal. Watching him adapt to Hawaii’s looser, more collaborative approach is gold.
Jane Tennant (Vanessa Lachey)
Tennant’s commanding presence and emotional intelligence shine here. She’s protective of her team — and skeptical of Parker’s sudden involvement.
Ernie Malik (Jason Antoon)
Tech genius Ernie gets some hilarious yet sharp exchanges with Parker, who’s not exactly fluent in “Ernie-speak.”
Kai Holman (Alex Tarrant) & Jesse Boone (Noah Mills)
The muscle and field savvy. Expect fast action, undercover work, and some testosterone-fueled banter.
A Sneak Peek at Key Scenes
The Arrival – Parker’s Culture Shock
Parker’s first moments in Hawaii? Let’s just say… Hawaiian shirts aren’t his thing. He’s all business while the island vibe is all chill. The contrast makes for some hilarious, tense moments.
The Big Bust – Guns, Grit, and Tension
The teams team up on a high-stakes raid, complete with shootouts, intel hacks, and split-second decisions. It’s classic NCIS with a tropical twist.
A Moment of Mutual Respect
In a quiet scene post-mission, Parker and Tennant find common ground. It’s subtle but powerful — the kind of moment that shows why crossovers matter.
The Hawaii Setting Adds Depth
Paradise Meets Procedural
The lush scenery, local customs, and tight-knit community vibe give this crossover a fresh layer. Parker’s rigid approach clashes with Hawaii’s cultural sensitivity — and it leads to growth.
More Than Just a Backdrop
Hawaii isn’t just a setting — it’s a character. The island influences decisions, behavior, and even the way the team works cases.
Themes That Elevate This Episode
Trust Across Teams
This episode isn’t just about catching bad guys. It’s about learning to trust, even when styles differ.
Communication, Island Style
In Hawaii, it’s not always what you say — it’s how you listen. Parker has to slow down and adjust. And in doing so, he becomes better.
Interconnected Stories
The crossover also hints at a larger threat — something that could span both shows in future episodes.
