"NCIS: Los Angeles" puts the team on a deadline with next week's 518, "Zero Days," for which CBS released a new sneak preview on Tuesday, March 18.
In this next "NCIS: LA" episode, it's up to the team to figure out if the computer system that controls Russian missiles is at risk after Eric (Barrett Foa) overhears his friend, a computer systems expert, being attacked during online game play. Is someone going to try to redirect a missile?
Meanwhile, in Afghanistan, Kensi (Daniela Ruah) is shocked when a familiar face from her past shows up. The last episode, "Between the Lines," saw Kensi go off on her own to find the White Ghost, and she was waiting in a cave to see him. Matthew Del Negro guest stars as Jack, and in case you forgot, Jack was Kensi's fiancé who left her on Christmas.
The "Zero Days" promo focuses on the case in L.A., as the team has 31 minutes to save America. They have to secure the satellites, but they won't be doing that without running into some trouble – and Eric's out in the field with them.
Plus, don't forget to check out the slideshow for the promotional photos CBS has released from this episode, especially to see Eric's awesome pants and two new images showing what's going on in Afghanistan.
"NCIS: Los Angeles" season 5 airs Tuesdays at 9 p.m. on CBS. What do you think of the episode 18 "Zero Days" photos and promo?
