This film by Yannick Bacher tells the passion of brothers Frédéric and François Nicole for climbing. Through the sites of Cuzzago (Italy), Zurich, Murg, Pelzli, Montreux, St-Loup, Yverdon-les-Bains, Saint-Triphon or Erde, we learn to know these 2 living legends better, their life choices, their philosophy... United by blood ties, those of fraternity but also by the same passion, that of the rock, of climbing. Fred made climbing history by pushing back the difficulty ladder in the discipline of bouldering. François him, founded a family and carried out a parallel professional career. But both have never stopped exploring, traveling and climbing.
