The film is based on events in the childhood of the director, Louis Malle, who at age 11 was attending a Roman Catholic boarding school near Fontainebleau. One day, he witnessed a Gestapo raid in which three Jewish students and a Jewish teacher were rounded up and deported to Auschwitz. The school’s headmaster, Père Jacques, was arrested for harboring them and sent to the concentration camp at Mauthausen.
