Adventurous nine-year-old Johanna senses something is not right in her working-class community of Wels, where an idyllic façade hides historical traumas. Events take a dramatic turn when Johanna discovers that her anguished mother and blind grandmother are Jewish, having survived the war under assumed identities. Rather than let sleeping dogs lie, mother and daughter must decide whether to live in continued isolation, or allow Johanna to reveal her true heritage under her real name, Hanna.
