The 11th season of NCIS: LOS ANGELES continues where the Season 10 cliffhanger left off. Callen (Chris O'Donnell) and Sam (LL COOL J) are aboard the USS Allegiance working alongside Navy Captain Harmon Rabb, Jr. (David James Elliott) to apprehend spies aboard the ship, Deeks (Eric Christian Olsen) and Kensi (Daniela Ruah) are trapped in a mobile CIA unit in Iraq under attack by an ISIS platoon, and Hetty (Linda Hunt) has recruited Lieutenant Colonel Sarah 'Mac' Mackenzie (Catherine Bell) to help neutralize a missile attack in the Middle East.
