Dive into the mind of French mountaineer Charles Dubouloz as he achieves Rolling Stones (5.10 A3, or M8, 1100m) a rarely repeated route on the fabled north face of the Grandes Jorasses above Chamonix, France. He spent six days with five bivouacs on the wall, pressing on through strong winds and low temperatures of -30°C (-22°F), sustaining some frostbites to achieve one of the most acclaimed winter solo ascent in the Alps. « I'm scared, I quiver, I'm cold...but I have this intense drive to set foot on the summit. »
