"Person of Interest" is about an ex Special Forces soldier, John Reese (Jim Caviezel) who is right on the brink of committing suicide when Harold Finch, (Michael Emerson) rescues and recruits him to help save lives. Harold creates "The Machine" which acts like the NSA listening and seeing everything. It finds people who are either going to kill someone or are going to be killed. The machine communicates with Harold and spits out a random sequence of letters which happens to be a social security of a random person. John works as the bronze while Harold is the brains of the operation.
