Eighteen years ago, Billy Peters disappeared, and everyone in town believed he was murdered by serial killer Arnold Avery who admitted to killing six other children and burying them on the same desolate moor that surrounded Billy's village. But Billy's mother is convinced he's still alive, and her twelve-year-old grandson, Steven is determined to heal the cracks that gape between his nan, his mother, his brother and himself by bringing the family closure even if it means personally finding his uncle's corpse himself.
