In this crime thriller, a former CIA agent, John Reese (Jim Caviezel) teams up with mysterious billionaire Harold Finch (Michael Emerson) to prevent violent crimes before they happen. 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. Also working with Reese and Finch are detectives Carter and Fusco (Taraji P. Henson & Kevin Chapman). With infinite crimes to investigate, Reese and Finch find that the right person, with the right information, at the right time, can change everything.
