Claire was just a child when her best friend was abducted and murdered. Twenty-five years later, the killer has served his time and is due to be released. Claire is approached by Bill, the dead boy’s father, who has a plan to keep the killer behind bars. With the help of psychic Eleanor, he takes them deep into the haunted moor which he believes is his son’s final resting place. They find more than just the ghosts of dead children out there - something else, something dark and evil, stirs beneath their feet.
