Chamonix-native climbers Joel, Olivier, Georges and Marshall immerse themselves in the crystal oven, a so-called crystal cave, for the crystal picking tradition of Mont Blanc. Using their binoculars to examine cracks in the wall, they discover the possibility of finding a crystal cave in the Leschaux area and eventually succeed in gathering enormous amounts of highquality crystals. An unusual story about discovering and experiencing pure joy through the simple act of journeying up a mountain they love so much. (Christine PAE)
