It’s a lifelong dream about Alex Honnold, the rock climber who wants to realize his dream: the free solo climb of the most famous rock face of the world, the 1 kilometer high El Capitan in Yosemite National Park. The incredible and literally nerve-racking story of a man with a mission. At the age of 30, Alex Honnold was known as one of the most talented mountaineers of his generation. By climbing the rock free solo, without rope or any other tool, Alex reaches a certain focus, a state of being, which is everything for him. He was seen in adventure magazines and wrote the memoirs ‘Alone on the Wall’. But he remains obsessed with a challenge never achieved by a climber: climbing the cliff of El Capitan in the California Yosemite National Park, without safety cables in a life-threatening climb to the top.
