Every year, over a thousand climbers try to reach the summit of Mount Everest, with the annual record for successful attempts currently standing at 633. But of that number, nearly half were Sherpas - the mountain's unsung heroes. Yet the Sherpa community has remained secretive about their nation, culture and experiences living in the shadow of the world's highest mountain. Now, for the first time, they open the door into their world. Without the expertise of the Sherpas, only the hardiest and most skilful climbers would succeed. Every day they risk their lives for the safety of others, yet they seek neither glory nor reward, preferring to stay in the background. Following the stories of four such Sherpas - Phurba, Ngima, Ngima Tenji and Gelu - this film reveals the reality of their daily lives, not just up the mountain, but with their families after they return home.

March 12, 1987. The young French mountaineer Eric Escoffier prepares his equipment, very reduced in material and food. He leaves the next day and intends to chain three north faces in the Alps: Eiger, Matterhorn and Grandes Jorasses. The ascent of the first summit, the Eiger is slow, difficult and full of pitfalls. It takes 17 hours to reach it. Without recognizing the terrain -he prefers to improvise- the mountaineer continues through the Matterhorn. When night falls, anxiety is felt on Zermatt's side. Help is organized to pick him up. Despite his refusal to return, Escoffier is finally hoisted. Christophe Profit, a few hours earlier, managed the chain of three summits.
