Reunited with estranged husband and undercover cop Phil Broker, Nina Pryce takes an extended medical leave from the army to recover from the injuries-physical and psychological-she sustained at the hands of a vicious psychopath. The Broker/Pryce household relocates to a remote resort town of Glacier Falls, MN, where daughter Kit is enrolled in second grade at the local elementary school. Everyone assumes that Kit is adjusting well-until she punches Terry Clump, the terror of the second grade, in the face. He gets a bloody nose and she gets suspended. What begins as a seemingly minor spat between innocent kids quickly escalates into a vicious scenario of lawlessness and provocation. Kit's imitation of her parents' violent proclivities has put them all in harm's way: the Clumps are but one-half of a notoriously vengeful "clan" known for criminal behavior and brutal violence.
