Based on the real events of the 1996 Mount Everest disaster, Jason Clark plays Rob Hall, experienced climber and leader of commercial expeditions up the mountain. His group, Adventure Consultants, is one of several making the trip. Another, led by party boy Scott Fischer (Jake Gyllenhaal) leaves at the same time, and agrees to share resources on the trek. Climbers include Beck Weathers (Josh Brolin), Doug Hansen (John Hawkes), Yasuko Namba (Naoko Mori) and journalist Jon Krakauer (Michael Kelly). Some reach the summit, others do not, but the trick isn’t getting to the top, it’s getting back down again, and that’s where the drama really begins.
