Zavvi - The Home of Pop CulturePERSON OF INTEREST is a crime thriller about a presumed-dead former CIA agent, John Reese, who teams up with mysterious billionaire Harold Finch to prevent violent crimes with high-tech surveillance and their own brand of vigilante justice. Reese\'s special training in covert operations appeals to Finch, a software genius who invented a program, aka The Machine, that can identify people soon to be involved in violent crimes. Tapping into ubiquitous surveillance feeds throughout the city, the two work outside of the law, combining Reese\'s black ops skills with Finch\'s technological prowess and unlimited wealth to unravel the mystery of the person of interest, and stop the crime before it happens. Reese\'s actions draw the attention of the NYPD, including by-the-book homicide detective Joss Carter. After initially pursuing Reese as a criminal, Carter now shares in his pursuit of justice. Also working with Reese and Finch is Detective Lionel Fusco, a onetime corrupt cop who began as Reese\'s unwilling pawn, but now views their missions as a chance at personal redemption. With infinite crimes to investigate, Reese and Finch find that the right person, with the right information, at the right time, can change everything.
