In July 1960, a woman went missing in the St. Gallen Rhine Valley, never to be seen again. She was a psychiatric patient and the mother of seven children who had all been taken into care. The story of Maria Theresia Wilhelm and her husband Ulrich Gantenbein is a tragic tale, marred by violence and the arbitrary actions of public authorities.
