Morgan Freeman explores the mysteries of divine visions and the people who claim to have them. He travels to Lourdes, France, to meet a woman who believes she was cured of paralysis by miraculous waters; to London, to meet a man whose divine visions followed a life-saving surgery, and to Canada, to meet an Anishnaabe man who endured days alone in the wilderness for the sake of divine vision
Some faiths have secret rituals only for special initiates, while others hide their entire religious communities. Morgan Freeman travels the world to uncover why secrecy and religion are often intertwined. He explores a villa in Pompeii that housed the secret cult of Dionysus and heads to the mountains of Nepal, where Buddhist monks have secret mantras just for select groups.
