The 15th season of the hit action police procedural series "NCIS" is fast approaching its finale, and the upcoming episode will feature the main protagonist's team in a deal with a murderer.

According to a synopsis of the series' upcoming episode 15 titled "Keep Your Enemies Closer," Leroy Jethro Gibbs (Mark Harmon) and his NCIS team will work with "convicted murderer Paul Triff, giving him 48-hour furlough at his former residence." Incidentally, the home is now where Tim McGee (Sean Murray) is residing.

The deal will be struck "in exchange for information that can convict his former cellmate, Gabriel Hicks (Graham Hamilton), the murderer who deceived Gibbs and (Tobias) Fornell," the synopsis from TV Maze added. The episode will also feature other actors like Pauley Perrette (who plays Abby Sciuto), Maria Bello (who plays Special Agent Jacqueline "Jack" Sloane), Wilmer Valderrama (who plays Nicholas "Nick" Torres), and Emily Wickersham (who plays NCIS Special Agent Eleanor "Ellie" Bishop).

Furthermore, the International Business Times (IBT) reported that guest stars like Fran Bennett (who portrays Mary Elaine Smith) and Stephanie Arcila (who plays Danielle), and Hilary Ward (who portrays Jessica Shaeffer) will be joining the recurring cast in episode 15.

Other characters that are part of the 2018 cast appearing in the upcoming episode include David McCallum as Dr. Donald "Ducky" Mallard, Brian Dietzen as Dr. Jimmy Palmer, Duane Henry as MI6 Officer Clayton Reeves, and Rocky Carroll as NCIS Director Leon Vance.

Back in Episode 14, Gibbs and his team received orders from Vance to work with Fornell, who was a former FBI agent and is now a private investigator. Fornell was hired to search for a missing Navy commander, whose body was eventually found, leaving the former searching for answers behind the high ranking officer's mysterious death.

"NCIS" season 15 episode 15, titled "Keep Your Enemies Closer," is set to air on Tuesday, Feb. 27, at 8 p.m. ET on CBS.
