The NCIS team in New Orleans will be under a huge amount of pressure in the season 3 finale of "NCIS: New Orleans."

According to the synopsis of the finale episode called "Poetic Justice," Pride (Scott Bakula) and the team will call on a reinforcement from the FBI to help stop the evil plans of Mayor Douglas Hamilton (Steven Weber) for the people who are living in Clearwater.

The synopsis reveals that to succeed in their plans, the team will contact FBI Assistant Director Isler (Derek Webster) because they cannot trust anyone in the city anymore. But aside from closing the case and exposing the mayor's evil plans, the season finale is expected to conclude the long-standing feud between Pride and Hamilton.

Based on an interview with TV Guide, executive producer Chris Silber revealed that the fight between Pride and Mayor Hamilton has gotten very personal. "Hamilton has finally proven that he can bite back, and he's targeted in on Pride's team. And they're really going mano a mano. Pride's losing his cool over it. It's gotten way too personal for him," the executive producer stated.

But the result of the fight between the NCIS special agent and the city mayor will be further tackled in the show's season 4.

"Obviously our Dwayne Pride has taken the side of righteousness on this but he's willing to sacrifice everything to stop Mayor Hamilton once and for all," Silber also said. "And yes, the question will become for Season 4: What are the consequences of that for Pride after, one hopes, he does accomplish that mission?"

The executive producer also revealed there will be several new faces who will make an appearance in "NCIS: New Orleans" season 4, as well as the return of some of the show's old favorites.

CBS will air the finale of "NCIS: New Orleans" season 3 on Tuesday, May 16, at 10 p.m. EDT.
