In 1941, under the Vichy regime, during the Nazi occupation, a team of six people crossed the Mont-Blanc massif. Leaving the Arve Valley with a month of supplies, five young men and a woman attempt a raid to show that France has passion and love for the effort and to celebrate youth, teamwork, leadership, tradition and achievement. The team advances roped, above the clouds. They pass the different passages, glaciers and needles, sleeping in tent under the stars at minus 20°C, facing the storms and the dangers represented by crevasses. Among others, they climb the Aiguille Verte, the Aiguille du Grépon and Mont Blanc.
