A Line Across the Sky

The Fitz Roy Traverse is one of the most sought after achievements in modern alpinism: a gnarly journey across seven jagged summits and 13,000 vertical feet of climbing. Who knew it could be so much fun? Join Tommy Caldwell and Alex Honnold on the inspiring -- and at times hilarious -- quest that earned the Piolet d'Or.

Starring: Tommy Caldwell, Alex Honnold
