Inspired by the incredible events surrounding an attempt to reach the summit of the world's highest mountain, the film documents the awe-inspiring journey of two different expeditions challenged beyond their limits by one of the fiercest snowstorms ever encountered by mankind. Their mettle tested by the harshest elements found on the planet, the climbers will face nearly impossible obstacles as a lifelong obsession becomes a breathtaking struggle...

A group of friends on a climbing vacation ignore warnings that the mountains are closed and start their ascent anyway. Collapsing bridges, bear traps, and other dangers threaten to splinter the group, when the real hell begins and an unseen villain begins picking them off one by one.
