Based on the letters left by their parents, André-Lilian and Réjane Mossé retrace the path trodden by their mother, Francine, and father, Christian, murdered by the Nazis because of their Jewish origins. The Mossé family was originally from Angoulins-sur-Mer, western France, who, following the defeat of 1940 found themselves in the forbidden coastal area. Living in Paris, Francine and Christian took refuge in Marseille with their children. The visit of Francine at Angoulins in a zone under high surveillance rendered the whole family suspect of espionage.
