Emma Greene enjoys living in rural solitude with her husband and five-year-old daughter, Maggie, far away from her college students in Jackson, Virginia. But late one night, with her husband away and her daughter upstairs in bed, some of Emma’s students trespass on her property. The ensuing confrontation changes Emma and Maggie’s life forever. Nine years later, still plagued by nightmares from that evening, Maggie is living with her father in the same small town, and entering her first year of high school. She develops problems in class when her math teacher, a strange and lonely woman, begins to exhibit an odd interest in her. In order to let go of the past, Maggie begins to piece together all the truth of what happened that night—and discovers a story of anger, guilt, and redemption.
