Hetty’s (Linda Hunt) life will be in danger in “NCIS: Los Angeles” Season 11, episode 10. A preview video of the next episode shows the case this time will be about a former agent who will return to seek revenge.

According to the plot synopsis, a former black ops agent who goes by the name of Akhos Laos will return to seek revenge. Hetty was the one who recruited Akhos back then and trained him. He, however, will be angry with her for introducing him to this kind of life.

A preview video of the next episode shows the agents calling the bomb squad to check a suspicious package. The attack, however, will not be through a bomb. Akhos appears to be an expert who has the ability to use cyber attacks to cripple the agency’s infrastructure.

There will also be some fun moments in the next episode, where the agents will get to hang out and play some basketball. A clip from “NCIS: Los Angeles” Season 11, episode 10 shows Callen (Chris O’Donnell) and Sam (LL Cool J) teaming up against Kensi (Daniela Ruah) and Deeks (Eric Christian Olsen).

The agents play a friendly game, but Callen appears to be cheating in order to win. The fans won’t get to see who wins the game because Eric Beale (Barret Foa), who will not be happy about being left out, will break up the game with news about a security breach.

The next episode is special because it marks the 250th for the TV series. A special behind-the-scenes video has been released online that shows the cast and crew celebrating the milestone by having a party and a beautiful cake.

“NCIS: Los Angeles” Season 11, episode 10 is titled “Mother.” It will air on Dec. 1 at 9 p.m. EST on CBS.
