John Anderton, a Washington, D.C. detective in the year 2054 working in "Precrime," a special unit of the police department that arrests murderers before they have committed the actual crime. Precrime bases its work on the visions of three psychics or "precogs" whose prophecies of future events are never in error. When Anderton discovers that he has been identified as the future killer of a man he's never met, he is forced to become a fugitive from his own colleagues as he tries to uncover the mystery of the victim-to-be's identity.
