The team re-examines an ambush on a group of Special Ops snipers six months ago in Iraq, after an American couple is attacked in the same area. When Gibbs discovers he needs the account of the lone survivor, he tries to connect with the wounded warrior who is being treated for PTSS at Walter Reed Medical Center.

Laura San Giacomo returns as Grace Confalone. The episode features a special performance by the MusiCorps Band, part of a music rehabilitation program for wounded veterans.
