Starting from a photo and a box in an attic, director Magnus Gertten’s film tells the unlikely love story of two women who meet on Christmas Eve 1944, in the Ravensbrück concentration camp. When Nelly’s granddaughter decides to go through some of her later grandmother’s things, the epic tale unfolds of Nelly and Nadine. The film charts both the life they lived before they met and their incredible journey after. This documentary takes you on a journey of survival, espionage, tragedy and most of all, love.
