Jost Kobusch

27-year-old German alpinist Jost Kobusch wants to climb Everest, alone, without oxygen and in Winter, when the roof of the world is deserted.

“Roche” from father to son… Bertrand Roche, nicknamed Zébulon, the spring-loaded character from The Magic Roundabout, comes from his inability to stay still. At 11, he reached the summit of Mont Blanc, which he has since climbed more than fifteen times. At 12, he took up paragliding and, in the United States, climbed the famous Nose face of El Capitan in Yosemite with his father, Jean-Noël Roche, known as Pap’s, a renowned Himalayan mountaineer and paraglider. He was filmed during this journey by Philippe Lallet and became the central figure in the documentary film Pap’s and Zébulon, as well as in the book written by Jean-Noël Roche and Claude Roche: Pap’s and Zébulon, or, The Extraordinary Adventures of a 12-Year-Old Mountaineer.

In Tamazight culture, "Twïza" symbolizes a gathering for sharing and mutual support. This is precisely what Thibault Dion's film explores – January 2019 – as five French climbers land at Constantine airport. While they initially thought they would simply be opening climbing routes in eastern Algeria, this group of climbers from Grenoble discovers much more. Their initial apprehension about exploring this isolated region, coupled with the warm welcome, good humor, and rich culture, transforms their journey into an unexpected human adventure. Fabulous landscapes, thrilling experiences, unforgettable moments, smiles – beyond borders, in the land of friendship and hospitality... Algeria.

In October 1984, Pierre Béghin, an engineer from Grenoble, and Jean-Noël Roche, a high-mountain guide, completed the Himalayan ascent of Dhaulagiri (8,172 m). The expedition's context: seven people crossed Nepal to Muri, collected accounts from trekkers—including that of the author Robert Rieffel—and attended Sherpa prayers at base camp. Then, the two of them embarked on a rocky and snowy route without supplemental oxygen. At over 5,000 meters, on the mountain of winds, Jean-Noël Roche made a paragliding flight. The climbers brought back footage with their Super 8 camera from 6,500 meters, but only photographs have been able to confirm their presence on the summit ridge of the seventh highest peak in the world.

On April 29, 1983, three French alpinists reached the summit of Jannu, having climbed its 7,710 meters via the very steep southwest spur. The success of Luc Jourjon, Jean-Noël Roche, and Roger Fillon echoed that of the 1962 national expedition, which had been celebrated by Lionel Terray alongside the leading climbers of the time, Desmaison, Paragot, Magnone… But in 1983, the goal was no longer simply to wave a French flag on a virgin summit. The focus was already on a more "alpine" style, and there was even the idea of ​​descending from the top… by air!

Avid for steep slopes, Marco Siffredi (1979-2002) obeys only one rule: not to fall. This gifted kid with hair sometimes blond peroxidized, green or blue clashed in his valley: Chamonix, mecca of mountaineering. His thing was to go up and down on a snowboard. . 90 minutes September 8, 2002, altitude 8848 meters, rare oxygen, his head already brushing the sky and his snowboard running, Marco Siffredi, 23, rushes from the summit of Everest in the Horbein corridor and its slopes at 50 degrees . A year earlier, he had already made the first descent of the mountain on a snowboard. But there remains another corridor… more direct. It's not a challenge, just a reason to be... However, that day, at the top of the roof of the world, his trace is lost...

The first winter ascent of Nanga Parbat was achieved in 2016 by Pakistani Muhammad Ali Sadpara and Spaniard Alex Txikón, accompanied by Simone Moro and Tamara Lunger. Alex Txikón made headlines again by attempting K2 in the winter of 2019, then Everest in the winter of 2020 (each time unsuccessfully); but also by participating in the search operations led by Tom Ballard and Daniele Nardi on Nanga Parbat in March 2019, even claiming to have spotted two figures on the face. Confined during the Himalayan season, the Basque climber took the opportunity to work on a film recounting his own adventure on Nanga Parbat four years earlier.

In 1915, the First World War is in full swing and young men are called to military service in rows - including Franz and Peter. Both are sent to the Dolomite front, in order to fend off a threatened Italian attack. Comradeship and loyalty are needed in the fight, but Franz and Peter are ever enemies. Since Peter's romance with Anna, the competition between the two flares up more. But the circumstances of the war and the harsh weather in the mountains soon end those hostilities.
