The voice of opera singer Nelly resonates in the middle of the Ravensbrück concentration camp. Nelly and Nadine met for the first time at Christmas in 1944. They found each other again after liberation and were to stay together for the rest of their lives. Today, Nelly’s granddaughter Sylvie is about to be confronted with her grandmother’s legacy, locked in a box. The photographs, Super 8 footage and audio recordings, as well as the poetic and harrowing diary entries that she comes across, describe not only her grandmother’s memories of the camp, but also tell the story of her life with Nadine – a relationship that was never referred to as such by the family.
