Fania worked at the Union, the Munition factory in Auschwitz, and one day, she arrived to work on her shift and found the tiny heart, which was really a birthday card that unfolded into tiny sections, all signed with wishes from the other girls working as slave laborers.
Somehow, at the risk of getting caught and risking her life, she kept the heart and eventually donated it to the Montreal Holocaust Memorial Center.
Carl Leblanc, who made the documentary, was so intrigued by the little heart that he embarked on a journey to find the person who made the heart and some of the women who signed the card.
During his search, he travels to many places. At first, there is a lot of scepticism that this heart is real because, as explained by some witnesses, it would have been virtually impossible for the girls to make such a thing that required paper, scissors, material, and that all the girls, if caught, would have been killed. Then it would have been impossible for Fania to be able to hide the heart because the girls were searched daily from head to toe.
Carl Leblanc puts the pieces of the puzzle together and goes back in time to, little by little, reveal the secrets of the heart.
Great research work by Carl Leblanc. It is a very touching movie.
