Sur Le Fil Des 4000

The documentary follows the mountaineering duo as they embark on a unique expedition, aiming to traverse the Alps while carrying out their climbs on foot, skis, or bikes. Their journey began on March 1, 2004, from Saint Christophe en Oisans, showcasing the beauty of the alpine landscape during winter and spring.

This film features a focus on the enjoyment of the mountains rather than the competitive spirit often associated with climbing. It provides a glimpse into the world of alpinism and the challenges faced by climbers in extreme conditions. The film is significant as it was edited posthumously after the tragic disappearance of Patrick Berhault during this very expedition, adding a layer of poignancy to the adventure.
