When billionaire software guru known simply as Mr. Finch develops a software program for computers that helps identify someone who potentially will become involved with violent crime he intended the program to help locate terrorists in our midst and prevent another disaster such as happened on September 11, 2001. As they work with the software it is soon learned there are other uses for it. The program can be set to detect those who run the risk of being involved in some sort of violent crime but cannot tell if those involved will become victims or perpetrator or simply witnesses to the crime. While crimes cannot be stopped before happening they do find it helpful in solving and making arrests. Helping Mr. Finch (Michael Emerson from Lost, The Practice) solve these crimes is John Reese (Jim Caviezel of Outlander, The Prisoner), formerly with the CIA and now presumed to be dead. Mr. Finch is also thought to be deceased and the two have worked out a plan to locate those singled out by the software program by use of their social security numbers.
