Take a part to an expedition of the prestigious High Mountain Military Group to the farthest ends of Patagonia. United by their passion for the great outdoors, they pay tribute to the heroes of the Aéropostale by climbing the three pinnacles, or Agujas, of the Monte Fitz Roy range that bear their names: Mermoz, Saint Exupéry and Guillaumet. All thrill-seekers, the viewer accompanies these mountaineers from Chamonix all the way to their ultimate homage: a base jump from one of the pinnacles! Considering the unpredictable nature of the wild, will they be able to rise to the challenge? One century after the beginnings of the Aéropostale, this unique one-off offers us a fantastic tribute to brotherhood and self-transcendence.
