For several years, athlete Hillary Gerardi has shone on the podiums of the biggest trail races, but her gaze is set on high altitude. Victim of a terrible accident a few years earlier, she questions her legitimacy as a mountaineer to measure herself against the most prestigious mountain running record. The round trip starting from the church of Chamonix, the capital of mountaineering, to the summit of Mont Blanc. Secretly, Hillary has dedicated her last three years to this meticulous preparation, but that was without counting on climatic hazards that are much less controllable than her own determination... On the eve of the International Year of Glacier Preservation in 2025 (UNESCO), this inspiring film harmoniously combines the sporting performance of Hillary's record and the awareness of the importance of glaciers through the speech of glaciologist Heidi Selvestre.
