This gritty “NCIS” spinoff moves the action from Washington, D.C., to the sun-soaked West Coast, where undercover agents G. Callen (Chris O’Donnell) and Sam Hanna (LL Cool J) pool their talents to guard U.S. interests for NCIS’s Los Angeles Office of Special Projects Division. Rounding out the team are operations manager Hetty Lange (Linda Hunt), psychologist Nate “Doc” Getz (Peter Cambor) and forensic investigator Kensi Blye (Daniela Ruah).
