A tightly spun, atmospheric and powerful psychological suspense. Living in a remote Devon farmhouse, Anna and her family have always been close to nature, surrounded by the haunting beauty of the moor. But when a convict escapes from nearby Dartmoor prison, their isolation suddenly begins to feel more claustrophobic than free. Fearing for her children's safety, Anna's behaviour becomes increasingly irrational. But why is she so distant from her kind husband Robert, and why does she suspect something sinister of her son Paul? All teenagers have their difficult phases ... Meanwhile, a young idealistic teacher has just started her first job, determined to 'make a difference'. But when she is brutally attacked by one of her students, her version of events is doubted by even those closest to her. Struggling to deal with the terrible consequences, she does what she can to move on and start afresh. As the two narratives converge, the tension builds to a devastating denouement, shattering everything you thought you believed about nature, nurture and the true meaning of family.
