Joseph Toloche, his wife Flore Boudin and their children Marguerite and Bernard are arrested in Rouen (German-occupied France), where they had fled during the invasion of Belgium by German troops. They are interned in detention camps and Flore Boudin dies of a miscarriage. Father and children flee back to Belgium and are deported from there to the Auschwitz-Birkenau concentration and extermination camp. Only Joseph Toloche survives.
