Inheritance (2006)
Inheritance is a 2006 documentary film about Monika Hertwig a.k.a. Monika Christiane Knauss, the daughter of Ruth Irene Kalder and Amon Goeth, Commandant of Kraków-Płaszów concentration camp. Monika Hertwig was 10 months old when her father was hanged in 1946 for war crimes, crimes against humanity and genocide. She discovered the truth about him only as a young adult, because her own mother told her in childhood that he was a good man and a war hero.
