It is a film is about many things. It is about freedom and captivity, about emancipation, acculturation and assimilation; it is about the roles played by Moses and Felix Mendelssohn in the dream of fruitful, unproblematic integration of the Jews into German society after their liberation from the ghettos; it is about Richard Wagner, his ferociously anti-Semitic essay Das Judenthum in der Musik (The Jews in Music) and his influence on the thinking of the Third Reich but, most of all, it is a film about how much music can mean to people, even in the direst of circumstances, or particularly in the direst circumstances.
