The Ring of the Buddha: Nepal 1950. A mysterious, unexplored country. The Swiss geologist Toni Hagen, was the first European to pass through the "forbidden" kingdom. He doesn't discover any mineral resources there. Yet he does uncover the mysteries of life and penetrates towards a more profound truth which lends a new dimension to his life. In the spring of 1999, Hagen returns to Nepal to keep a promise of almost 50 years: At that time a Buddhist monk had presented him with the gift of a valuable and mystical ring.
