Absorbing documentary about the disastrous 2008 summit of K2, the most dangerous mountain in the world, more dangerous than Mount Everest, when 11 climbers lost their lives to an avalanche. Some stunning raw footage of climbers falling down the mountains. Really heroic of the sherpas to rescue many climbers, while two sherpas died in the process. The climbers delayed while reaching the summit, which in turn made their descent that much more difficult. It is said in mountaineering that the descent is the most difficult and dangerous and more people have died while coming down.
