The series tells the story of a former CIA agent who is "legally declared dead" and is hired by a mysterious billionaire to play the card of autonomous justice and use private power to fight crime and protect people. Caviezel's character is named Reese, and his special training in covert operations caught the attention of Emerson's character Finch. Finch is a software genius who invented a program that can use patterns to identify groups of criminals who are about to commit violent crimes. Using this state-of-the-art surveillance technology, the two men are outside the law, using Reese's skilled agent skills and Finch's unlimited wealth to uncover the mysterious suspect and stop the crime before it happens. Reese's actions have attracted the attention of the NYPD-New York Police Department, including homicide detective Carter, and Fusco, a police officer who Reese once used. And Reese and Finch discovered that in this era where private privacy is exposed wantonly and everyone is monitored by the government's "Big Brother", as long as the information is used correctly, at the right time, and the right person is found, crime can be stopped and everything can be changed. CBS has renewed the third season
