This Oscar-winning documentary tells the story behind Japanese daredevil Yuichiro Miura's 1970 effort to ski down the world's tallest mountain.

Ueli Steck (Switzerland), Simone Moro (Italy) and Jon Griffith (GB) are not like 95% of the climbers on Everest: they don't use oxygen, altimeters (improperly called Sherpas), or fixed ropes. In 2013, the trio aims to repeat the arduous Western Spur. The Sherpas have the mission to equip the mountain with fixed ropes on this famous day, up to Camp 3: ropes without which customers of commercial expeditions could not climb Everest. An argument ensued, insults were hurled from both sides. The confrontation at Camp 2 degenerated: a Sherpa water bottle physically attacked the trio of Europeans. Blows and stones were thrown and threats led the trio to flee the mountain. The Réel Rock film crew, which is part of the climbing team, films this chaos without complacency.

Yûichirô Miura, the man who skied down Everest, journeys to an 8,000 foot mountain in the midst of a frozen antarctic wasteland to experience the incomparable thrill of skiing where no one has skied before.

In this documentary, Bear Grylls takes us on a journey through the most extreme version of the world's highest and most legendary peak: Mount Everest. Several leading figures in mountaineering and extreme sports, for whom a standard ascent is no longer enough, transform Everest into a laboratory for extreme challenges. Told through archival footage and reenactments, this elite group seeks new forms of performance, attempting to ski the slopes, snowboard down them, hang-glide or paraglide above the summit ridge, open new routes on more technical and exposed faces, and break climbing records. The documentary also highlights the essential role of the Sherpas, the colossal logistics behind each attempt, the explosion of commercial expeditions, and the moral debate surrounding the ever-increasing risks involved in breaking records or achieving unprecedented feats.
