A team of 12 men, 5 sailors, a doctor, a writer, a film crew, and 3 mountaineers, Jean-Marc Boivin, Thierry Leroy, and Dominique Marchal, set off by sailboat from Mar del Plata in Argentina to reach Riso Patron in Chile, via the Strait of Magellan, the Patagonian Channels, and Falcon Fjord. Their goal is to climb Riso Patron and then make the first crossing of the Campo de Hielo Sur glacier, or Hielo Continental Patagónico, to meet up with the sailors in Puerto Williams on Navarino Island in Chile, a village at the end of the world. After three attempts and an accident for Leroy, who was repatriated, they gave up, crossed the glacier and rejoined the boat, to set off for Cape Horn to climb the South face, knowing that the weather was good one day a month... On January 20, 1983, Jean-Marc Boivin and Dominique Marchal succeeded in making the first ascent of the South face of Cape Horn.
