The NCIS:LA team is shaken when Assistant Director Owen Granger interrogates Kensi after the suspicious death of Marine Sergeant Chris Blake. Blake used to be the spotter for Kensi's father, Donald Blye, a special ops sniper, and it appears that his death was no accident. Blake is the latest in a string of mysterious deaths of men who were part of Donald Blye's unit, and it is revealed that Kensi was the last person to talk to many of them, making her the prime suspect in the case. Kensi is taken into custody while the team searches for a way to prove her innocence, but she escapes and sets out on her own to find the real killer. Sam and Callen follow the evidence and track down Alec Harris, a CIA agent and former handler of Donald Blye's unit who claims to have information about Donald's death. The catch: he'll only speak with Kensi. The team sets up a meeting with Kensi and Alec at the old Griffith Park Zoo, but it's interrupted by an unseen sniper who kills More...Alec and manages to hit Kensi in the chest.
