What does it take to climb the world’s first 9c? Bernardo Giménez' documentary shows what preceded on the afternoon of September 3, 2017 when professional rock climber Adam Ondra made a little piece of climbing history by sending his project in the Hanshelleren Cave in Norway. The route, eventually named Silence, received a new grade of 9c making it the hardest route in the world.
Is Silence on Netflix? Unfortunately the movie Silence is not yet available on Netflix.
