The story of a friendship for life and death captures a real event that took place in the snowy Krkonoše Mountains in 1913. The actors of the drama were Bohumil Hanč, one of our first ski racers, and his friend Václav Vrbata. The film's plot takes place between 1912 and 1913 and is framed by two international 50 km races. After winning in 1912, Bohumil Hanč wants to stop racing at the behest of his wife Slávka. In 1913, strong foreign competitors enter the race, so Bohumil succumbs to the pleas of his friends and decides to race for the last time. However, the weather changes during the race. Strong winds and snow begin to blow, severe frost sets in, and for the racers, it means a fight for their lives.
