Since the disappearance of his son Sean, PreCrime Captain John Anderton has separated from his wife Lara and becomes a drug addict. While United States Department of Justice agent Danny Witwer is auditing the program, the Precogs generate a new prediction, saying Anderton will murder a man named Leo Crow in 36 hours. Anderton does not know Crow, but flees the area as Witwer begins a manhunt. Anderton seeks the advice of Dr. Iris Hineman, the creator of PreCrime technology. She reveals that sometimes, one of the Precogs, usually Agatha, has a different vision than the other two, a "minority report" of a possible alternate future; this has been kept a secret as it would damage the system's credibility. Anderton resolves to recover the minority report to prove his innocence.
