The Matterhorn is one of the world’s most famous mountains — and amongst the deadliest. Since it was first ascended in 1865, over 600 climbers have lost their lives on the peak. Despite modern infrastructure and global awareness of the risks, tragedy strikes the Matterhorn again and again. This film asks why so many climbers misjudge the risks. Death on the Matterhorn follows mountain guide and head of rescue operations, Anjan Truffer, up to Solvay Bivouac — one of the mountain's high-altitude huts. It shows how Edith Lehner, warden of the nearby Hörnli Hut, lives with the losses. The crew also accompanies climber Meli Rüfenacht on her first ascent of the Matterhorn — one year after she herself witnessed a fatal fall.
