NCIS: New Orleans season 7 episode 15 is going to be the final one before the police procedural drama officially wraps up on CBS. The penultimate episode is titled "Runs in the Family" and it will build up a lot of big stories leading to the series finale.

NCIS: New Orleans season 7 episode 15 is bringing a romantic storyline for Dwayne Pride (Scott Bakula) and Rita Deveraux (Bakula's real-life wife, Chelsea Field). Despite the chaos surrounding them as of late, the two have finally decided to plan for their wedding.

However, they won't be able to properly plan it as huge trouble is about to happen. The major problem here is that Pride's son, Connor (Drew Scheid), gets arrested -- putting Rita in a very difficult position in NCIS: New Orleans season 7 episode 15.

The penultimate is going to be the biggest one for Field ever since her character was promoted as a series regular. She is in a situation where she needs to make a wise choice. She loves Pride, but she also recognized that he has to be there for his son.

As the synopsis of NCIS: New Orleans season 7 episode 15 notes, the FBI arrests Connor the time Pride and Rita plan their wedding. The former was arrested due to his connection to the firebombing of the bar, which was believed to have been orchestrated to get to his mother, Sasha Broussard (Callie Thorne).

What makes the situation more complicated is that Rita might be the only person who can save them. It looks like this storyline will continue until the final episode, though it remains to be seen whether or not all of them get the ending that they deserve.

Meanwhile, the wedding of Pride and Rita is set in "a down-home backyard bash" -- with the bride wearing red. The event will be quick since the health of the groom's mother, Mena (Joanna Cassidy), is declining due to Alzheimer's disease.

All of the guests will gather in the garden of Loretta Wade (CCH Pounder) and the reception is at Pride's beloved Tru Tone bar. But then, the celebration turned sideways because of the appearance of the criminal mastermind, Sasha.

She has been Pride's nemesis since the first season, and he found out recently that they have a son. Their relationship was revealed in episode 12, titled "Once Upon A Time." Their son, Connor, is musically talented like his father. Their twisted past will be further explored in the remaining two episodes.

NCIS: New Orleans season 7 episode 15 airs on Sunday, May 16, on CBS.
