Premise
The show follows a team led by Harold Finch, a reclusive programmer who created a government computer program called the Machine. The Machine predicts crimes by mining all sources of information and identifies both victims and perpetrators of premeditated crimes. The government considers many predictions “irrelevant,” so Finch has the Machine delete those numbers each night and secretly alerts himself to the relevant ones to stop violent acts.

Season arc and storylines
- The season splits its focus between Carter’s investigation into corrupt police HR and the expanding story of the Machine, which becomes more self-aware and active in guiding the team.
- A major new element is Samaritan, a more powerful AI that can be directed from outside and is willing to remove threats to order preemptively. Samaritan ends up in the hands of Decima.
