But as a psychotherapist trying to help patients heal after traumatic events, she knows only too well that it's impossible to recover from some losses. Just as she's starting to forget the scars of her past, Madeleine is thrown off-balance by the arrival of a new patient. Sensing something familiar in this damaged and hostile woman, Madeleine is disturbed to discover that strains of her patient's childhood eerily echo her own darkest secret. The increasingly complex relationship between Madeleine and her client, Rachel, will unleash a terrifying series of events which neither could have predicted - and which neither can control. And at the heart of the terror lies the fate of a child.
