<P> Person of Interest centers on a mysterious reclusive billionaire computer programmer named Harold Finch ( Michael Emerson ) , who develops a computer system ( known as `` The Machine '' ) for the U.S. government that is capable of collating all sources of information to predict and identify -- in advance -- people planning terrorist acts . He finds that the Machine also identifies other perpetrators and victims of premeditated deadly intentions , but as these are considered `` irrelevant '' by the government , he programs it to delete this information each night . He soon realizes the Machine has developed into a sentient superintelligent artificial intelligence , leaving him wrestling with questions of human control and other moral and ethical issues resulting from the situation . His backdoor into the Machine allows him to act covertly on the non-terrorism cases , but to prevent abuse of information , he directs the Machine to provide no details beyond an identity to be investigated . He recruits John Reese ( Jim Caviezel ) , a presumed - dead former CIA agent , and later others , to investigate and act on the information it provides . </P>
