The Austrian professional freerider and adventurer Matthias 'Hauni' Haunholder and Matthias Mayr set off to follow the traces of pioneers who had skied down famous Alpine mountains for the first time – and they are impressed. They are even more surprised, when they consider the materials of that time. Observed by a state-of-the-art camera, the two professional skiers try to repeat the partly extremely exposed descents. Due to the climate warming, some ski runs have become even more extreme, or already impossible. They experience thrilling moments on the north face of the Hochfeiler in the Zillertal Alps or in the Pallavicini Gully on the Großglockner.
