A family of athletes, some professional, others simply enthusiasts, but all of them driven by the same passion: ski mountaineering. A sport that demands effort, training, spirit of sacrifice, an iron will and character. These are fundamental qualities if one wishes to participate in the Mezzalama Trophy. Through the life of the Cazzanelli family, father, son and daughter, we will discover three different ways of participating in the event. With its landscape, windblown ridges at an altitude of over 4.000 metres and athletes, the true protagonist of the documentary is the Mezzalama Trophy itself .
