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 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...

After reading the book "Guide to Hoggar Climbing," guide Pierre Agresti and his wife Isabelle Agresti set off into the Hoggar massif in the Algerian Sahara and tackled the west face of Garet El Djenoun. After a first attempt in 1967, they successfully reached the summit in 1970 and, with an old camera, made a film that remained unused for 25 years. In 1996, they decided to bring the past back to life through the ascent and encounters with the Tuaregs in the rock salt mines of Amadror. The film was shown in competition at the Trento Film Festival in 1997.

Less than two years after his serious road accident, Eric Escoffier brought together the "Turbo" team (Frédéric Ancey, Michel Fauquet, Christine Janin and Stéphane Schaffter) with whom he will attempt to climb Everest without oxygen and without prior acclimatization in the Himalayas, the project being to complete the Paris-Everest-Paris loop in two weeks. It is also a medical experiment: the athletes spend a week at Mont Blanc, at the Vallot observatory between 4000 and 4800m, then a week in a hypobaric chamber in Grenoble. Doctors (Dr. Richalet, Herry and Bittel) perform tests throughout this training, which will learn about how the body acclimatizes to altitude and allow applications in the management of mountain-related illnesses . On September 2, 1989, they arrived at Everest base camp in China. They attempted the ascent via the North Col but could not carry out their project, prevented by bad weather.

Filmed chronicle by mountain filmmaker Mario Fantin, of the 1964-1965 expedition of the Italian mountaineer Guido Monzino to the summits of Hoggar in the Algerian Sahara with the ascents of Garet el Djenoun, Tizouyag Nord, Saouinan and Iharen. The mountain ranges of the Hoggar desert turn out to be more complex and interesting than most mountaineers suspected at the time.
