“The Commandant’s Shadow” follows Hans Jürgen Höss, the 87-year-old son of Rudolf Höss, as he faces his father’s terrible legacy for the first time. His father was the Camp Commandant of Auschwitz and masterminded the murder of over a million Jews; the life of Höss and his family was recently fictionalized in the Academy Award-winning “The Zone of Interest.” Now, “The Commandant’s Shadow” tells the story of the real people who lived on site at Höss’s death camp.
