This surveillance system is known as P.E.A.C.E., Police Enforced Anti-Crime Environment. There are special undercover police officers who work with the system. They are known as sleepers. Since the inception of this new system crime has drastically declined and most citizens are thrilled with it. The P.E.A.C.E. system is being tested in New York before going nationwide, so it's critical to his political plans that nothing go wrong.
Nothing seems to be amiss until two sleepers are involved in an accidental shooting.
Mac Wells inadvertently shoots his partner, Sam Mullane. After waking up, Sam appears to be fine, at least for a while. It's not long after the shooting that Mac begins to discover that there's something going on within the P.E.A.C.E. organization. As he uncovers the facts and gathers information, he realizes that the justice system isn't as just as he'd thought. He's uncertain about whom to trust and he knows it's only a matter of time before they get to him and his wife.
