Based on the Jack Ketchum novel and also on the actual horrific events, this is the harrowing story of Sylvia Likens. Two sisters, go to live with their mentally unstable aunt Ruth after the death of their parents. All seems well at first but Ruth's depraved sense of discipline leads to unspeakable acts of abuse and torture that involve not only her other children but also others from the neighbourhood. The Girl Next Door draws its nerve-wracking, gut wrenching power from a real-life horror show - described in court as "the worst crime ever committed".
