NCIS: Scope

The NCIS team re-examines an ambush on a group of Special Ops snipers in Iraq after an American couple is attacked in the same area six months later. When Gibbs discovers he needs the account of the lone survivor, Marine Gunnery Sergeant Aaron Davis (Taye Diggs), he tries to connect with the wounded warrior who is being treated for PTSS at Walter Reed Medical Center, on the 300th episode. 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.
