This breathtaking film follows an historic attempt to summit the world's most challenging peak on the 100-year anniversary of the Duke of Abruzzi's landmark K2 expedition in 1909. World-class alpinists Fabrizio Zangrilli and Gerlinde Kaltenbrunner team up with veteran climbers Jake Meyer and Chris Szymiec in a dangerous foray of high altitude mountaineering.

The documentary also examines the history and geography of the Karakoram mountains while contemplating the risks, rewards and personal nature of exploration in an age when there are few blank spots left on the map. The second highest peak on Earth at 8,611 meters, K2 is also one of the most dangerous mountains to climb: for every four people who have reached the summit of K2, one person has died trying.
