In a series first, tech operator Eric Beale (Barrett Foa) goes undercover tonight on CBS’ NCIS: Los Angeles to ensure classified technology remains secure after a rocket-engine expert is killed.

He got to  ‘NCIS: Los Angeles’: Barrett Foa talks Eric’s first undercover mission (and secret relationship with Nell?)
