Are dark, supernatural forces at work in the idyllic world Nathan Appleby has created? When the death of his mother brings pioneering psychologist Nathan Appleby (Colin Morgan, The Fall, Merlin) and his adoring wife Charlotte (Charlotte Spencer, Les Misérables) back to his family’s estate in the isolated Somerset valley, strange and inexplicable events begin to swirl around the increasingly troubled Nathan. His beliefs that a rational, scientific explanation is available for all of life’s mysteries are put to the ultimate test as he’s confronted with one disturbing case after another. Are these strange events just coincidence, or is this tiny rural village actually plagued by a much more sinister force? The answer may not be something Nathan is prepared to accept.
