"NCIS" season 14 will focus on Ellie Bishop (Emily Wickersham) as she gets an unexpected visit and a case that leads her back into her past.

In episode 8, "Enemy Combatant," Emily's three brothers will surprise her for Thanksgiving. Their idea of surprising her is marching to her place while she is not in.

This is why when she hears other people in the place when she heads home, she locks and loads her gun to take down the intruders, as seen in the promo for "NCIS" season 14 episode 8.

However, it looks like it will be a chore for Emily to have her brothers around the house. A promotional still from the episode shows them lying around the place, eating, drinking, and watching the television.

Clearly, Emily is not at all thrilled. CBS even teases in another "NCIS" season 14 episode 8 image that the trio have "a lot to ponder" after their sister speaks to them about what they are up to.

It will be interesting to see how the brothers will react on Emily dating, which was hinted in the promo. Her team members are dying to know who she is seeing.

Even McGee (Sean Murray) and Abby (Pauley Perrette) want to know the details. The synopsis of "NCIS" season 14 episode 8 teases that the brothers will actually "pester" Emily's co-workers to know the identity of the guy that captured the heart of their sister.

However, it seems that Emily is not really up for the idea of talking about her love life as she even denied to Quinn (Jennifer Esposito) that she is going on a date.

Meanwhile, the episode will also see Emily take on a case involving the murder of a Navy chaplain. To learn more about it, she is sent to Gitmo.

This leads her to question her previous work at the National Security Agency (NSA). As fans know, she worked there as an analyst. She was brought into the NCIS team by Agent Gibbs (Mark Harmon) after Bishop's theory about the mole turns out to be accurate.

How that links to the case at hand will be revealed on Tuesday, Nov. 22 at 8 p.m. ET on CBS.
