In autumn 1987 a Polish-Italian expedition, led by Krzystof Wielicki sets up the base campt at the foot of the south wall of Lhotse, an impressive wall that man has not been able to climb so far. All the strongest and best trained mountaineering teams in the world have tried to climbe it but they have always failed. The snowslides obstruct the progress of the expedition. One of these hits a group of alpinists who are climbing to camp 1 and the doctor of the expedition is killed and others are injured. Nevertheless they manage to set up camp 6 at 7,900 m, but then it starts to snow. Wielicki and Hajzer reach 8,300 m, the highest point ever reached on this wall but here they have to give up because of bad weather.
