A little girl's silence rends a small North Carolina community. When her silence continues into her college years, the country divides over her message.
Hannah, age 6, gradually stops talking. Her mother, having already lost her husband, is battling for her sanity and losing again. Adults interpret the girl's silence in unpredictable ways, and conflicts erupt between different factions in the church, the school, and the community. A judge rules her mother unfit and Hannah is placed in foster care. Tracked by a group who believes she is evil incarnate, while another group believes she is a prophet with a message from God, the state sends her into hiding after an attempt on her life. Growing up with her foster family, the danger and controversy finally die down. When Hannah starts college, her identity is discovered, remnants of both groups emerge, and yet another organization forms - an anarchist group that views Hannah as their role model.
Politics heat up as presidential candidates' opinions on Hannah and her various followers become a campaign diversion from more serious issues. As the entire country takes sides on whether Hannah is a visionary, an anarchist, or demonic, she tries to disappear again, wanting only to find her mother. One word could put an end to the chaos, if Hannah can find her voice.
