The character of Claire Vallant was inspired by French photojournalist and Auschwitz survivor Marie-Clause Vaillant-Couturier

"May 1940 - Paris. On the eve of her eighteenth birthday, Claire hears the devastating news: the German army has invaded her homeland, and her beloved Paris has fallen. Within months, her life is turned upside-down. She takes in an orphaned Jewish toddler only days before her beloved German-born husband Remy is forcibly conscripted into the Nazi army. In desperation she connects with other young members of the French Resistance, determined to fight back in whatever way she can. Armed only with her wits and her 35mm camera, she looks for the one photograph that will expose the Nazi horror for what it is. When her rebellion is discovered and Claire is sent to Auschwitz, she knows her moment has arrived. A Nazi officer, hiding in the shadows of Auschwitz, commits an unspeakable atrocity, a war crime. Can Claire help bring down the beast who emerged from Auschwitz? Or will her secret evidence die with her as the SS hunts her down?" --
