4 Savoyard friends have a crazy idea: 50 days of autonomy in Alaska in the Denali massif. Les Jours Sauvages takes us to the rhythm of a logbook in a quest where friendships are invented and put to the test of commitment, where time expands and spirits fly away. Hélias, Alex, Christophe and Aurel all live in Chamonix. This cradle of world mountaineering and expert skiing is their daily playground. They have all participated in long, difficult expeditions at high altitude. They have bivouacked on the face or gotten lost on gigantic Himalayan glaciers, dug an igloo to shelter from storms. Waiting, doubts, giving up, and success are stages and feelings that they know and whose lessons they know how to appreciate. They are also full of willpower, strength, spirit and good humor.
