Kennan has been chained in his parents' attic, held prisoner for over thirty years. Having been born a disfigured mute, he has been caged in order to protect him from "a world that he can never be a part of." When his mother dies, his brother, Karl, moves into the house with his wife and two daughters and becomes Kennan's caretaker. For a year, Karl's wife, Diane, puts up with her "retard" brother-in-law. But when she tires of the situation, she delivers her ultimatum: Karl's family or his brother. Who will Karl choose? And will Kennan ever be free? Until the family secret is released, the Wesley's will forever be Muted.
