The NCIS and NCIS: New Orleans special crossover will air tonight, Jan. 5!

Pauley Perrette Divulges 'NCIS' Has 'A Scuba Script' Coming Up!

Actress Pauley Perrette, the portrayer of Abby Sciuto, is absolutely excited--and so are we!

In the first hour of the crossover, viewers will tune in to the NCIS episode "Sister City: Part One," in which Gibbs (Mark Harmon) and his D.C. team will work with Pride's (Scott Bakula) New Orleans team to locate Abby's brother Luca (Tyler Ritter) after a private plane's entire crew and passengers are lethally poisoned while traveling from New Orleans to Washington D.C. Luca happens to be the missing chef from the private airliner.

Plus, they'll all be working to figure out why a private tech company was targeted to begin with.

The NCIS YouTube channel released two sneak peeks before the episode debuts tonight, which can be seen below.

In the first sneak peek, the D.C. team is video conferencing with the New Orleans team as well as Navy Captain Kensington Bloom (Wendy Davis) about the private aircraft.

Suddenly, Pride walks away from the video conference and calls Gibbs in so they can "talk privately," since he received the flight's manifest.

"Dwayne, what's going on?" Gibbs asks.

"Flight manifest just came through," Pride states, before slowly adding, "Gibbs we, we got a problem. Fifth name on the list: Luca Sciuto. Abby's brother was on that plane."

Gibbs ends the call while speechless before looking over at Abby.

Then in the second sneak peek, Abby frantically calls Luca to prove he's alive.

"Luca, I know you're not dead, okay, so call me back," she says while leaving a voice-mail.

Gibbs then tries to make sense of the situation with her.

"Luca never leaves NOLA! He doesn't like to fly!" Abby declares, before asking, "Are you sure about this?"

Abby then reveals he would have let her know he was coming to D.C. unless he was attempting to surprise her.

"Stop putting thoughts in my head," she then demands, adding, "Luca and I, we don't get to see each other in person that much, you know cause we're both super dedicated to our jobs, but if Luca were dead, I would feel a disturbance in the force. You know that's very strong in my family!"

Gibbs finally gets in that Abby should go to the crash site.

NCIS airs on Tuesdays at 8 p.m. ET on CBS.
