Many years after World War II, evidence showing a connection between Swiss policy and the deportation and murder of Charles and Sabine Sonabend's parents at Auschwitz fall into Charles's hands. This startling film documents the journey of the brother and sister back to Switzerland, where they confront people from their past, including a former government border official and a nun from a monastery where the children briefly were hidden. The insensitive and intolerant attitude of these Swiss people is shocking.
