Highest danger level on the railway line to Gornergrat in Switzerland. The hotels on the mountain are snowed in, skiing has come to a standstill. For the men of the clearing party, this means one thing above all: hard work and high personal commitment, because the fight with the elements harbors great dangers. Wind speeds of 150 km / h have created snow drifts and the danger of avalanches. So far they can only guess what is coming up there. With their gigantic snow blower, a Beilhack HB17G from 1970, the men cut their way up the mountain. With zero visibility and constant threat from slabs and avalanches, they try to fight their way up to the mountain station at an altitude of 3,100 meters. A mission with an uncertain outcome.
