Reinhold Messner, the world's greatest mountain climber, looks back over his career with surprising candor and self-revelation. It is the career of a man who began climbing with his father in the exquisite Italian Dolomites, but whose restless quest for self-knowledge through extreme adventures made him the most accomplished climber of modern times. MESSNER includes rare film of his astonishing climbs of the world's highest mountains - without using bottled oxygen and often alone.
