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.
