NCIS: Hawai'i has only just started airing but it is already set to have a special crossover episode with its parent show NCIS.
Wilmer Valderrama, who plays NCIS Special Agent Nick Torres, announced the exciting news alongside his fellow cast members via a joint video message shared on Instagram for fans.
Here is everything you need to know about the crossover episode.
Who is starring in the NCIS and NCIS: Hawai'i crossover episode?
Valderrama was joined in his video message by Katrina Law, who plays Jessica Knight opposite him in the CBS flagship show.
Law confirmed her involvement before claiming it was "going to be good to be back on the island solving crimes."
The pair will be joined by NCIS Hawai'i cast members Vanessa Lachey, Yasmine Al-Bustami, Tori Anderson, and Jason Antoon, all of whom appeared in the video.
Lachey said she'd be "the best host" for them, and Al-bustami said she was excited to be "investigating together."
While they did not appear in the announcement, NCIS Hawai'i's main cast members Alex Tarrant and Noah Mills, who play Kai Holman and Jesse Boone respectively, are also expected to take part.
When will the NCIS and NCIS: Hawai'i crossover episode air?
Lachey confirmed in the announcement video that the episode will air on CBS on Monday, March 28.
It has not yet been revealed how long the crossover episode will be, or if it'll be the standard 45 minute episode or longer.
In an interview with TVLine before the announcement, NCIS showrunner Steven D. Binder said he's "worked and known [NCIS: Hawai'i co-showrunner] Chris Silber for a really long time, so that always makes those sorts of things easier."
Silber also told the publication that a crossover would only be on the cards when the show's first season had finished airing.
NCIS Hawai'i is confirmed to have 12 episodes so far in its first season, with the 12th episode airing on Monday, January 24.
What will the NCIS and NCIS: Hawai'i crossover episode be about?
The storyline for the special crossover episode has yet to be confirmed, so it is unclear what circumstances will lead Valderrama's Torres and Law's Knight to join the team in Hawai'i.
While a plotline has yet to be announced, it's likely the Hawai'i team will have a case that can only be solved with the help of Torres and Knight.
A trailer for the crossover event has yet to be revealed, but it is probably too early for there to be one given NCIS Hawai'i has not yet reached its Season 1 finale.
