Maurice Baquet was a musician of the highest caliber, a member of the Groupe Octobre, a fantasist, a stage performer, a film actor, a mountaineer and a skier. In fact, he once described himself as a "cellist-skier", "all alone" in this category, prompting world champion skier James Couttet to say: "Of all the skiers I know, he's the best cellist"; echoing this, André Navarra, Professor at the Conservatoire National Supérieur, went one better: "Of all the cellists I know, he's the best skier". To talk about Maurice and all his adventures, who better than his alter-ego: Cérébos, the faithful cello that never left his side. From Paris to Chamonix, from theater stages to granite slabs and snowy slopes, we follow Cérébos, cross the century and, above all... smile!
