Erin Moore, kidnapped as a teenager and held for months, learns her abductor is up for parole. The police always believed her captor acted alone, and that the female accomplice Erin described years ago was the fabrication of a traumatized mind. Twenty years later, Erin leads a rigidly structured life with her husband and two young daughters and has a successful psychology practice in the same small midwestern town. When her abductor is paroled early and goes missing, leaving behind a large pool of blood, Erin and her husband become suspects. Erin receives threatening notes she is certain came from the accomplice, but she is unable to convince the police the menace is real. As Erin watches her life unravel, including her marriage, career and possibly her sanity, she knows the only way out is to bring the accomplice to justice, even if it's twenty years late.
