The series revolves around a computer program for the federal government known as "The Machine" that is capable of collating all sources of information to predict terrorist acts and to identify people planning them.

Meanwhile, a harried Fusco (Kevin Chapman) is approached for help by rookie detective Jake Harrison (Gavin Stenhouse), who is investigating the murder of Tara Cooke.
Reese (Jim Caviezel) and Shaw (Sarah Shahi) check surveillance and find that the kidnappers are part of a Mexican cartel.
