In Plain Sight - Season 5 Episode 3

A former Navy SEAL who now works for an Indonesian warlord, is arrested when he poses as an FBI agent to track down someone the warlord wants dead. He's taken to WITSEC and is at first reluctant to accept because the man he works for and his partner, Bo will make sure he doesn't talk. He asks to go outside so Marshall takes him to the roof and he jumps down and escapes in Delia's car. They find the car just outside an Indian reservation, where they don't have any authority. But Mary and Marshall enter anyway. But a reservation cop finds them and tells they have to talk to the Chief of Police. He allows them to find the man but only if one of his cops goes with him. And the one he assigns is the one they had encountered earlier. They follow his trail but he doubles back to the car and shoots the Chief who was there. And it turns out the Chief is the father of the cop who is assigned to Mary and Marshall. Finding the man has just become personal for her.
