After the romantic moments of Special Agent in Charge Grisha Callen (Chris O'Donnell) and Anna Kolcheck (Bar Paly) in the episode last week, it is now the time of technical operator Eric Beale (Barrett Foa) and Intelligence Analyst Nell Jones (Renee Felice Smith) in the upcoming episode of "NCIS: Los Angeles" season 8.

Titled "Getaway," Eric and Nell will go on an undercover mission in episode 18 of the American action television series.

The official synopsis of the upcoming episode reveals that the US Treasury Department will face some big issues after they were hacked. With all the information at risk, Eric and Nell go on a secret mission as husband and wife in a couple's retreat in order to keep an eye on the suspects, who are tech-savvy husband and wife.

Eric and Nell have to do their best in pretending that they are an item in order to carry out their mission successfully. In the promotional preview of episode 17, it shows that they need to share one room and one bed. Although this is not a norm for them, the two need to put up a really convincing front in order to track down their suspects. Nonetheless, that seems to be the easy part of them, as the preview also shows "the couple" getting ready to kiss without awkwardness.

Back in the Naval Criminal Investigative Service (NCIS) office, Digital Forensics Specialist Dave Flynn (Scott Grimes) arrives from the NCIS satellite office in San Diego in order to back up the operations while Eric and Nell are away. Will Eric and Nell successfully catch the hackers?

"NCIS: Los Angeles" season 8 airs episode 18 on Sunday, March 19, at 8 p.m. EDT on CBS.

Meanwhile, the title and summary of episode 19 have also been revealed. Titled "767," the next episode will see Grisha and Special Agent Sam Hanna (LL Cool J) go on an undercover mission in order to catch a suspect who intends to sell intelligence. Episode 19 will air the following week.
