Une série de braquages ​​de banques et de vols de voitures ont effrayé les communautés du nord-ouest du Pacifique. Un seul agent du FBI estime que ces crimes n'étaient pas l'œuvre de criminels motivés par l'argent, mais plutôt d'un groupe de dangereux terroristes nationaux.

As baffled law enforcement scrambles for answers about a series of increasingly violent bank robberies, counterfeiting operations, and armored car heists through the Pacific Northwest in 1983, a lone FBI agent stationed in the sleepy, picturesque Idaho town of Coeur d’Alene comes to believe the crimes are not the work of traditional, financially motivated criminals, but a group of dangerous domestic terrorists inspired by a radical, charismatic leader plotting a devastating war against the United States government.
