Christmas is just around the corner, and the FBI team is getting prepared for the holidays. Unfortunately, before they get a much-deserved rest after the trials of Season 8 thus far, they have one more confounding case to solve. Next week will mark the premiere of the flagship procedural’s two-part Christmas storyline, with Episode 9, “Lone Wolf,” and Episode 10, “Wolf Pack,” airing across two hours on Monday night, December 15, on CBS. Ahead of the special event, Collider can exclusively share a new sneak peek from the first half that sets the stage for how a seemingly ordinary murder investigation can spiral into something far more sinister that threatens the entire city.

The footage opens on a briefing led by Castille (Alana De La Garza) in front of the entire team, addressing the case at hand. With a little assistance from Jubal (Jeremy Sisto), she unravels the tangled web of a murderer who seemingly used sex workers to seduce and steal from multiple victims before killing all three of them and taking the ill-gotten gains for himself. Such a scheme necessitates a search of all five boroughs of New York to find the culprit before any more women can be used and any other citizens can be robbed. While Jubal and Castille start casting the net, Maggie (Missy Peregrym) and OA (Zeeko Zaki) start interviewing the men who were drugged by the workers, each of whom paints a similar picture of one of the three women flirting with them before slipping something into their drinks. The curious part, however, is that they weren’t stealing cash, but a laptop, a work lanyard, and keys, signaling that whoever is behind the scheme may be seeking something far more valuable and sensitive.

What Else Can Viewers Expect From the ‘FBI’ Two-Part Holiday Special?

If that weren’t enough stress for FBI in one week, Jubal will also have another reason to worry about his son, Tyler (Caleb Reese Paul). During the investigation, the veteran agent will get a concerning call from Tyler that will pull at least some of his attention away from the case. Their father-son dynamic was spotlighted last season when Jubal bent the rules to help his son out of custody at the potential expense of his career. Now, Tyler may be in even more trouble, and their relationship could be put to the test once again. Whatever the case, it looks to be an explosive midseason finale on both a personal and professional level for the whole team.

FBI Season 8’s two-episode holiday special kicks off on Monday, December 15, at 8 p.m. ET/PT on CBS. Check out our exclusive sneak peek in the player above.
