Three weeks into the busiest season ever on Everest, climbers crowd the slopes. When a hundred climbers attempt to summit, a traffic jam in the death zone puts all of their lives at risk.
A violent weather front threatens to slam the door on the climbing season, giving Russell Brice 5 days to get his weakest climbers to the summit and back.
Climbers arrive at Everest Base Camp and quickly learn the dangers of the mountain when they hear about a Sherpa's condition. Climbers struggle to push their bodies to acclimate to the extreme altitude four miles above sea level.
Hundreds of climbers at Advanced Base Camp prepare for the climb. Acceptable weather is fast approaching and the expedition leader plans for an early summit, but he'll have to push both his Sherpas and climbers extra hard to be ready in time.
