On the anniversary of the start of the Nuremberg trials, 90-year-old Colette Marin-Catherine confronts her past by visiting the German concentration camp Mittelbau-Dora where her brother was killed. As a young girl, she fought Hitler’s Nazis as a member of the French Resistance. For 74 years, she has refused to step foot in Germany, but that changes when a young history student named Lucie enters her life. Prepared to re-open old wounds and revisit the terrors of that time, Marin-Catherine offers important lessons for us all. (Source: Guardian Docs)
