In the face of horrific living conditions, Jewish inmates of Terezin concentration camp-artist, musicians, poets and writers-fought back with art and music. Led by conductor Rafael Schachter, they re-imagined a Catholic liturgical work, Verdi's Requiem, as a condemnation of the Nazis. They performed for Nazi brass, singing what they dared not say. Six decades later, a new conductor and choir take Verdi's Requiem back to Terezin to bring the story of Schachter's artistic uprising back to life.
