Psychotherapist Frieda Klein spends her sleepless nights walking the streets of London. She sees the world as a messy, uncontrollable place, an attitude which is reflected in her austere, orderly life. When five-year-old Matthew Farraday is abducted, there is a desperate police hunt. Frieda cannot ignore the coincidence: one of her patients has recurring dreams in which he hungers for a child the spitting image of Matthew.
