It's called the most controversial climb in Yosemite history — and for years, Wings of Steel on El Capitan sat unrepeated. In June and July of 2011, 42-year-old Ammon and his 22-year-old partner Kait set out to change that with a second ascent of a route no one had touched since its disputed first climb in the 1980s. Assault on El Capitan tells the story of the wall, the ascent, and the feud that surrounded it.

Why This Film Matters: Every subculture guards its own history, and few do it as fiercely as big-wall climbing. This film digs into how reputations are made and broken, how controversy calcifies into legend, and what it takes to challenge a story everyone thought was settled. It's a study in perseverance, and in the courage to walk into someone else's fight and finish it.
