What makes a friendship fall to pieces? Two extreme mountain climbers are closely bound by their common ambition to climb the highest peak in the world in record time. Their joint ascent to the summit of Broad Peak in Pakistan requires mutual trust to be able to unconditionally rely on each other and pushes them to their physical and mental limits. But was it actually a common goal or did their goal become a competition against each other? The peak stands between them and becomes their personal Mountain of Doom. After their climb there is no more togetherness but, in its place, a deep wound.
