Person of Interest is an American television series that stars Michael Emerson of Lost playing a mysterious billionaire by the name of Mr. Finch, who had developed a computer program for the government that predicts the identity of people connected to violent crimes and terrorist acts that will take place in the future. With the government unconcerned about them, and unable to stop the crimes on his own, Finch hires John Reese (played by Jim Caviezel), a burned out ex-CIA black-ops operative with a past, presumed to be dead, to help Finch stop these crimes and save lives.
