FBI is rolling out a 2-part story line on December 15.

The episodes, “Lone Wolf” and “Wolf Pack” follow a storyline that sees the team making holiday plans while involved in a seemingly straightforward murder investigation. However, when that investigation takes a shocking turn, the entire city of New York is put at risk.

In the first hour, the team finds three slain sex workers inside a brownstone – they uncover the murderer has a larger plan in place that they must rush to stop.

Meanwhile, Jubal receives a concerning call from his son Tyler.

The episode was written by Jake Tinker and directed by Ludo Littee.

It airs Monday, Dec. 15 (8:00-9:00 PM, ET/PT), on the CBS Television Network, and streaming on Paramount+, and continues with the concluding episode “Wolf Pack” at 9.00 PM.
