As the city sizzles under the early summer sun, New York chief assistant D.A. Butch Karp and his family are happily vacationing on Long Island's north shore. Their reverie changes to horror when they learn that their beachfront neighbors, Rose and Ralph "Red" Heeney — a coal miners' union leader — have been brutally murdered back home in tiny McCullensburg, West Virginia. Irresistible force meets immovable object when the governor appoints Karp special prosecutor to bring justice to the corrupt rural town, its ruthless union boss, and his band of violent henchmen. Now, Karp finds himself not only searching for the killers, but fighting to protect his own family from an evil that runs as deep as the mines that fuel it.
