Set against the unforgiving backdrop of Annapurna Base Camp, a legendary mountaineering duo and married couple face a safety crisis before their most dangerous ascent yet. With a dangerously narrow weather window and treacherous routes ahead, absolute focus is the only way to survive a mountain known for its high fatality rate.

The fragile peace shatters when a volatile love triangle erupts into open hostility between Angus, a hot-tempered Australian, and Mathieu, a provocative French climber. Caught in the middle is Lenka, Angus’s fiancée, who desperately tries to defuse the situation. As the confrontation escalates under the anxious eyes of the Sherpas and crew, the expedition's collective safety hangs in the balance, as any distraction in the death zone is a death sentence.

This confrontation forces the expedition leader to confront ghosts from the past. Years prior, a painful infidelity had threatened to destroy the leaders' own marriage, but through the shared suffering of summiting Everest, they chose forgiveness and unity over personal grievance.

Now, with the indifferent mountain looming above, the leader stands at a critical crossroads. To ensure survival, they must make a definitive choice: draw upon personal history to forcefully reconcile the feuding climbers, or exercise absolute authority and expel all three from the expedition before the climb even begins.
