All the names of the accused are real. Abraham Trzebrucki, André Bréchet, Émile Bastard, Lucien Sampaix, etc.
Based on a true story.
The film is inspired by Hervé Villeré's novel "L'Affaire de la Section Spéciale". Neither the author nor the movie directors had access to the French legal archives. They had to rely exclusively on the records left by the German side.
Minister of the Interior for only 9 months from July 1941 to April 1942, Pierre Pucheu will be sentenced to death as early as March 1944 in Algers, by the French Resistance, partly because of his role in the Special Section affair.
