In the Season 7 premiere of NCIS: Los Angeles, “Active Measures” (Monday, Sept. 21, at 10pm ET/PT on CBS) Callen (Chris O’Donnell) goes rogue and embarks on a secret mission that leaves Sam (LL Cool J) and the team in the dark. Hetty (Linda Hunt) demands that Callen’s operation be shut down and tasks the team with finding him before he finds himself in over his head.
