What do the holidays have in store for NCIS' Office of Special Projects?

Probably not what they have in mind, although that's par for the course in their line of work. And fortunately, unlike this week's episode (see our NCIS: LA review from Tuesday), a key member of the team is back.

Callen, Sam, Kensi and Deeks spend Christmas aboard an aircraft carrier investigating a fellow NCIS agent's demise. Meanwhile, Nell and Eric make the most of the holidays back at the office and Hetty takes a trip.
