In Texas, a man goes to the electric chair for the kidnap, torture and murder of six small children. In Boston, Massachusetts, a nine-year-old girl has been admitted to ER, unconscious and full of morphine. When she comes round, she remembers nothing about herself or her past. The girl is adopted and raised as Melanie by Dr Harper Stokes and his wife, whose own daughter Meagan was tragically murdered. Twenty years later, someone is targeting the family, sending grotesque messages and gifts. And in an even more horrible twist, a journalist approaches Melanie and tells her that her birth father was the executed murderer.
