February 14, 1942. Jacques, 15 years old, is stopped by the Gestapo in Compiègne for possession of a firearm. He is deported to the Hinzert concentration camp in Germany on June 18th. Following the Liberation, Jacques does not return. His mother, Emilia, searches for a trace of him for 30 years, but in vain.
In 2015, intrigued by the family silence that had settled in over the years around this disappearance, Olivier Fély-Biolet plunged into departmental, national and international archives, in a quest to uncover the fate of his cousin. There he discovered the terrible journey of "Prisoner NN", and why no one could ever know what had become of him. The story of his disappearance, like that of thousands of opponents of the Third Reich, reveals a little-understood aspect of the regime of terror set up by Hitler between 1941 and 1944.
