Twenty-three year old Alex Honnold is taking the high-stakes sport of free solo climbing to new heights. Climbing truly massive walls without a rope, and zero chance of survival if he falls, Alex is calm and fearless (except when it comes to girls). But attempting the 2,000-foot wall of Half Dome, the greatest free solo ever attempted, would finally teach Alex the meaning of fear.
