In April 2018, seven people died on the famous Haute Route in the Valais Alps – frozen to death from exhaustion in snow and ice, just 1,800 ft (550 m) from a refuge hut. What happened? After two years of research, this film answers many open questions for the first time: through documentary testimonies from survivors as well as with the help of events reconstructed in fictionalised scenes.

For Sherpas – Die wahren Helden am Everest (Sherpas – The True Heroes on Everest), the director received the 2009 Audience Award.
