High in the heart of Chamonix, one of the world’s most iconic alpine playgrounds, mountain guide and Rab athlete Pierre Idris “Pim” Mehdi reveals what it truly takes to build a life in the mountains. A Guide’s Book follows Pim through steep ski lines, complex terrain, and the daily balance between personal ambition and guiding clients safely in some of the Alps’ most demanding environments. From his unlikely beginnings far from big peaks to earning his place in the Compagnie des Guides de Chamonix, Pim shares the passion, discipline, and humility behind the craft of modern alpinism. Blending striking cinematography with intimate storytelling, the film captures the mindset, preparation, and deep respect for the mountains that define a true guide.
