At 4,634 metres, the Dufourspitze of Monte Rosa is the highest peak in Switzerland — and the launch point for one of wingsuit flyer Géraldine Fasnacht's boldest dreams. 4634 Perception: The Mountain Within follows her preparation, her ascent, a snowboard descent of the Alps' longest corridor (the Marinelli), and the flight itself, as she pushes the limits of human gliding from the roof of the range. Why This Film Matters: Beyond the adrenaline, this is a meditation on how one athlete reads a mountain — the patience of the climb set against the fleeting freedom of flight. It's a portrait of mastery, fear, and the strange calm of giving yourself to the air above an alpine giant.
