Plot summary

The Fez Festival of World Sacred Music brings Muslim, Christian and Jewish performers together at historic sites in Morocco, a country where the three faiths have lived in relative peace for centuries. Groups come to the festival from Morocco, Ireland, Russia, Afghanistan, Mauritania, the United States, Portugal and France. A Moroccan sufi guide calls what happens there the hearing of the heart, the oneness he places at the core of every religion and faith.
