In Plain Sight, Season 4

Mary:
[voiceover] Make no mistake: buying a car or copping a plea, deal making is a bloodsport. When a witness lands on my doorstep he's trading in his testimony, his hometown, and everyone he ever knew for a life at the end of the road. So we set him up; a new name, address, a job we hope he won't hate, but the one thing I can't give him, the deal I've yet to strike, is the one that protects him from the guy in the mirror.
