Watch Person of Interest

CBS's drama Person of Interest was one of the hit shows of the 2011-12 season. Starring Jim Caviezel and Michael Emerson, the show also features Taraji P. Henson and Kevin Chapman in supporting roles as homicide detectives. Harold Finch (Emerson) is a computer expert who, a decade ago, built a secret system for the government that predicts potential terrorist acts by spying on people every minute of their lives. It watches through hidden cameras, listens in on phone calls, reads e-mails, and tracks electronic transactions, using the information it gathers to detect potentially violent patterns that a human could never see. The machine predicts everyday murders, robberies, and other crimes as well, but the government disregards these, considering them irrelevant. Finch, however, refuses to accept this indifference, and has built a backdoor into the machine. Now it regularly delivers him the Social Security numbers of people it is watching, potential criminals or victims.

In order to carry out his plans, Finch enlists John Reese (Caviezel), a former military man and CIA agent fleeing a dark past. The challenge for Reese and Finch is to observe their "persons of interest," discover the signs of the upcoming crime, and act fast enough to prevent it before it happens.

Their task is complicated by the demons of Reese's past, including former CIA colleagues out to kill him, and the government conspiracies surrounding the construction and functioning of Finch's machine. Armed with Finch's wealth and computer wizardry, and Reese's fearsome combat skills, the pair have battled corrupt cops, Mafia gangsters, unscrupulous politicians, and more.

Person of Interest mixes slam-bang action and suspense with deft, low-key comedy and some Lost-style mysteries -- Reese and Finch's backgrounds are slowly revealed through flashbacks each episode. Caviezel and Emerson are both talented actors in their own ways and play off each other brilliantly, making charismatic heroes.
