Actor Masato Sakai brings you an unprecedented adventure! The world's first attempt to ski down the huge cliffs of Denali (6190m), the highest peak in North America. The challenge is undertaken by 40-year-old mountain skier Daisuke Sasaki. Denali is the mountain where Naoki Uemura, the adventurer he admired, lost his life. It has long been a dream of his to face it head-on. The temperature is minus 30 degrees Celsius and the oxygen is half that of the flat terrain. Will he succeed in his descent? The 4K camera captures the powerful footage. You, too, can join in on the ultimate adventure!
