A gunman seizes a nursery school, threatening to kill the teachers and children. The police are powerless, and the man makes no demands. Nobody knows why he has taken hostages or what he intends to achieve. The situation is complicated by the fact that a live broadcast from the nursery appears online. In desperation, the authorities ask for help from Gerard Edling, a former prosecutor who was dismissed from the service for disciplinary reasons. Edling is a specialist in kinesics, the branch of science that studies non-verbal communication. He is known not only for his eccentricity but also for his ability to solve any case. Or at least, that has been true until now… A game begins between pursuer and pursued, in which it is truly impossible to tell who is who.
