This is a true story. The mountaineer Peter Wehrli slips on the ice and falls during an excursion in the Ticinese Alps in January 1995. He loses consciousness and when he awakes, in the middle of the night, he doesn’t know where he’s. Over 50 rescuers are fighting against time to find him. On the morning of the third day, the rescuers who have been systematically searching screes, bushes, rocks, rivers and gorges in the whole area for 63 hours find him.
