The program explores the Kol Nidre, the most sacred prayer in Judaism that begins its holiest day of Yom Kippur. The Kol Nidre's words have caused centuries of persecution, but its poignant melody has enthralled generations of Jews and non-Jews and saved the prayer from itself. The program tells the Kol Nidre story impressionistically through the tales, the anecdotes, of those who have been touched by it, be they top experts on the chant or just those who have been changed by chanting it.
