Eleven-year-old Papik (nickname for Yannick Vallençant) dreams of climbing Mont Blanc with his father, Patrick Vallençant. After serious training, the adventure begins: they set off from the summit of the Aiguille du Midi, climb the ridge of the three Mont Blancs, bivouac at the Col de la Brenva, cross the Mur de la Côte and reach the summit of Mont Blanc. No child his age had ever before achieved this feat by this route.
