There are fourteen 8000 metre peaks: the Himalayan giants, a world where the air is so thin no human can survive for more than a few hours. Having already scaled thirteen of the Earth’s highest mountains, Sophie Lavaud is just one peak away from the Himalayan grand slam. Will she achieve her goal? The film immerses us in the world of high-altitude mountaineering, where climbers must tread the fine line between daring and vigilance. Sophie’s final challenge is a 40-day expedition peppered with setbacks. It is also a spectacular human adventure and an intimate portrait of disarming candour.
