Among the thousands of letters sent to the Vichy administration between 1941 and 1944, two almost identical letters addressed to Marshal Pétain were written one day apart in August 1942 by a young Polish man, Léon Kacenelenbogen. Interned in the Vichy camps, what became of the author of these two moving pleas? After weeks of research, we managed to learn that this young man survived. He eventually died at the age of 98 in Belgium. He never really told anyone what had happened to him. What took place during the life of this man about whom we know almost nothing? What kind of life did he have in the years between 1939 and 1948, when the world was turned upside down? The film will lift the veil on Léon’s extraordinary journey through Poland, Belgium, France, Spain, Palestine, and Israel.
