The team will deal with case that will be very personal to Sam (LL Cool J) in “NCIS: Los Angeles” Season 10, episode 20. Preview scenes and the trailer of the next episode tease the case to involve a Navy Seal.

The plot of the next episode revolves around a Navy Seal who is brutally attacked while working a security job at a successful marijuana dispensary. A trailer of the next episode shows Sam and Callen (Chris O’Donnell) visiting the injured man in the hospital.

As a former Navy Seal, Sam is angry about what happened to a fellow officer. Watching the man in the hospital with a tube in his moth drives Sam over the edge, and he will be “blinded” by his rage while investigating the case.

A sneak peek scene of the episode shows the Navy Seal using Morse code to communicate with Sam and Callan. Since he can’t speak he uses Morse code while blinking, and the first message he sends out is “SOS.”

“NCIS: Los Angeles” Season 10, episode 20 will be an explosive ride, as Sam takes on the case personally. Callan and his partner will have to face some gunfire while they go about the investigation.

Meanwhile, a major character of the show returns in full form in the next episode. A sneak peek scene shows Hetty Lange (Linda Hunt) back in the office.

Hette will spend some time quietly exploring the building in the next episode. The funny exchange between her and Eric Beale (Barrett Foa) revolves around her choosing an office space for herself.

Hunt had to miss out on some of the episodes in “NCIS: Los Angeles” Season 10 because of a car accident. She was able to make it to the wedding episode on the show, and may now be a regular face from the next episode.

“NCIS: LOS Angeles” Season 10, episode 20 is titled “Choke Point.” The episode is set to air on April 14 at 9 p.m. EDT on CBS Television Network.
