You are being-

We are being watched. The government has a secret system, a machine, that spies on you every hour of every day, I know, because Finch built it. He designed The Machine to detect acts of terror, but it saw everything, violent crimes involving ordinary people, people like you, crimes the government considered irrelevant. They wouldn't act so we decided we would, but I needed a partner, someone with the skills to intervene. Hunted by Samaritan, we work in secret, you will never find us, but victim, or perpetrator, if your number's up, we'll find you.
