Plot

Callen (Chris O'Donnell), having successfully recovered from his near-fatal shooting at the end of the back-door pilot episode, "Legend", rejoins the NCIS Office of Special Projects team whose headquarters have since moved to new surroundings and now under command of Operations Manager, Henrietta Lange (Linda Hunt). NCIS Director Leon Vance (Rocky Carroll) informs the team about the Naval Commander case, and the team realizes the Commander was executed. After following various leads, the team discover that the Commander's actions might have jeopardized a highly classified military operation against various drug cartels in Mexico and also his young niece is being held hostage. Callen informs Director Vance, but the Operation is still to be commenced. Callen and Sam infiltrate Manny Cortez's house, only to find out that the Commander's brother-in-law is the one responsible for the young girl being held as a hostage. Worse, Callen and Sam are compromised as Kensi previously spoke to the father as she and Nate were with the Commander's sister.
