As the 1987 trial of Nazi war criminal Klaus Barbie unfolds on television, Victor Bastien reviews old family documents and finds a distressing "Aryan declaration" authored by his late father. This new discovery throws Victor's conception of his family's history into darkness. His mother, Rivka, keeps a stubborn silence about the past, while Tania, his sister, defends their father's declaration. At the same time, Victor's wife and children grow concerned about his increasing distraction. Burning with the need to unearth the truth, Victor takes his family to the tiny village where Rivka's parents were forced to hide during the war.
