Promotional snap of "NCIS."

Something strange is about to happen in the coming "NCIS" season 15 episode 8 titled "Voices." The Naval Criminal Investigative Service (NCIS) agents are going to handle a different kind of case, and it will be like no other. 

Leroy Jethro Gibbs (Mark Harmon) is up to handle another strange assignment in the upcoming new episode of the long-running television show. As this case is described to be different from what the agents have been handled, they will be up to investigate the most unusual project.

In the official synopsis of "NCIS" season 15 episode 8 shared by Cartermatt, the NCIS' person of interest in a bribery and fraud case will be seen murdered. A runner is said to be led by a strange voice to find the suspect's lifeless body.

Now, it is a big question if an unknown voice could be accountable for this new murder in "Voices." Anyhow, this strange voice wants to assure that someone is going to find this dead body and let the NCIS team know about it.

On the other hand, Timothy McGee (Sean Murray) and Delilah Fielding (Margo Harshman) are having a disagreement whether they will know their baby's gender, so they could prepare, or just keep it a big surprise. Also, "NCIS" season 15 episode 8 will make way for the return of Mike Franks (Muse Watson).

Meanwhile, in an interview with TV Insider, Harmon addressed the rumors that he will be leaving "NCIS" season 15. The actor explained that as long as the action police procedural series' writers are still having fun doing the show, he would never do that. But, when the time comes that he will see their heads down when entering the writers' room, then that will be the moment he is also done playing the role of Special Agent Gibbs.

"But there is still a real feeling of creativity and a sense of reinvention on our set," he proudly said. He also talked about mysterious traits Gibbs has. Although the show is already in its 15^th season, fans are still not sure who Gibbs really is. He then described his role as a loner and a leader who has a lot of emotional scars — a person who is well reserved.

NCIS" season 15 episode 8 titled "Voices" will air on Tuesday, Nov. 14, at 9 p.m. EST on CBS.
