The Pledge

Not far from the sleepy Swiss village of Mägendorf, the body of young Gritli Moser was discovered in the woods; she had been the victim of a sexual offence and murdered with a razor blade. When Inspector Matthäi takes on the task of informing the distraught parents, he allows himself to be carried away into promising that the case will be solved. Soon, he loses himself in the investigation, becoming increasingly obsessed and careless.
