Lost in time, the Himalayan kingdom of Mustang is one of the last sanctuaries of authentic Tibetan Buddhist culture. Long isolated by geography and politics, the people struggle to survive; the center of their culture, the 15th-century monasteries and the art within, are dangerously close to collapse. Featuring His Holiness the Dalai Lama, the Raja of Mustang and chief art conservator Luigi Fieni, this program tells the compelling story of efforts to rescue this ancient place from the brink of extinction and help spark a cultural renaissance. Richard Gere narrates.
