Ground Zero in Manhattan has become a site of pilgrimage. Thousands of people visit the site, looking for consolation as they question the events of September 11. There is a profound quiet to their meditations. Starting here, FRONTLINE sets out on a ... (more)quest to find out how peoples' beliefs-and unbelief-has been challenged, and how they are coping with difficult questions of good and evil, the face of God, and the potential for darkness within religion itself. From survivors who were pulled from the wreckage of the Twin Towers to the widow of a New York City firefighter; from priests and rabbis to security guards and opera divas; from lapsed Catholics and Jews to Buddhists, Muslims, and atheists.... FRONTLINE explores and illuminates the myriad of spiritual questions that have come out of the terror, pain, and destruction at Ground Zero.
