NCIS: Los Angeles

CBS | 9:30 pm

David James Elliott and Catherine Bell reprise their old "JAG" roles as Navy Capt. Harmon "Harm" Rabb Jr. and Marine Lt. Col. Sarah "Mac" Mackenzie in the Season 11 premiere "Let Fate Decide," which picks up the tense action from last season’s finale. While Callen and Sam (Chris O’Donnell, LL Cool J) work with Harm to find and capture spies aboard the USS Allegiance, Mac teams up with Hetty (Linda Hunt) to neutralize a missile attack in the Middle East.
