Seven people froze to death from exhaustion, only 550 meters from the hut that would have saved them. What happened? The ski touring drama on the Haute Route of 29 April 2018, leaves many questions unanswered. Was it bad luck, was it human error, or was it recklessness? The drama under the Pigne d’Arolla, on the legendary Haute Route, is the biggest accident of its kind in the Swiss Alps. Based on the survivors’ testimonies, documents and photos, reenacted scenes, as well as GPS data and excerpts from the investigation report of the public prosecutor’s office in Sion, the film reconstructs the dramatic events of this tour and tries to find answers. For the first time, the three survivors, rescuers, as well as Steve House, the famous US alpinist, and two couples from France, who were all on the same route on the same day, talk about the drama and their point of view. Reenactments processed with VFX technology recount in detail what happened. The evening before the accident, the morning of the departure, the decision not to turn back, the early onset of the storm and the tragic night that ends fatally for seven of them.
