Watch Soap2Day. Probably no one has explored solo climbing like Hansjörg Auer, whose memorable feat on the "fish route" has forever marked the history of this very peculiar kind of mountaineering. "The hardest thing to do when you're doing free solo," says Hansjörg, "is not the ascent. It is to go back home." Why? Because when loneliness strips you naked you understand the importance of the relationships you build with people around you. “No turning back” is an introspective and epic film, delicate and powerful: there is not only vertical life, there is not only performance. There is an all-round discovery of what makes a life worth living.
