NCIS Season 6 Episode 8

Gibbs and NCIS Director Leon Vance shock the team by operating on a strict need-to-know basis in a fake break-in of a security building for top-secret Middle East contingency plans. It gets even intenser as they learn the real target is finding and trapping the mole who set up and murdered agent Langer, and proves quite able to fight back. Yet once the fiend is found, another problem arises, no less complicated, if the mole's motive can be believed.
