Gibbs goes into deep cover.
When Gibbs spots the brother of an "NCIS Most Wanted" suspect, he takes the opportunity to assume his former alias and go undercover with their infamous anti-government militia. This leaves the NCIS team to piece together where and what Gibbs is up to. Meanwhile, Bishop and Reeves partner up on an off-the-books investigation in the NCIS episode "Off the Grid."
Watch NCIS on Tuesdays at 8/7c on CBS and CBS All Access.
