en CB01 OFFICIAL. Seb Berthe dreams of climbing the Dawn Wall, the most difficult route in the world. To get to the foot of El Capitan, in the United States, Seb has no intention of taking a plane! Quickly, a team of 6 climbers, 2 sailors and a dog forms to take up a challenge and realize a dream: to reach the Americas on a sailboat to climb the legendary walls of Yosemite! It is by experiencing the long pace of sailing that they cross the Atlantic, then on board a dubious Mexican jalopy van that they learn to know each other. When they arrived at the foot of El Capitan, the team supports Seb in his extraordinary challenge. His push on the Dawn Wall becomes a collective climb. At the same time, everyone prepares to take up his own challenge and the feat takes place where no one is looking. The commitment and authenticity of a team that barely knows each other is reminiscent of the atmosphere of the first epic stories of vertical exploration.
