Mountaineer Benedikt Boehm and his partner Prakash Sherpa are undertaking a massive trek across Iran and Turkey to the peaks of Nepal. Experienced explorers and ambassadors for wildlife, they are studying the region's biodiversity in conditions of extreme heat and cold. The route stretches from tropical jungles inhabited by tigers and rhinos to snow-capped Himalayan peaks. The heroes challenge time by speed climbing to the highest points on the planet. The project is available for viewing in UHD.
