Two young guys parallel valleys and mountains equally. Their call is to become united with nature. Armin and Alessandro push their high limits when they perform high-lining. For this documentary, they have tightened a high line on the Monte Piana, in the Sextner Dolomites, where once upon a time, in the First World War, Italians and Germans fought against each other in a senseless war. Today, the Italian Alessandro d’Emilia and the German Armin Holzer from South Tyrol will cross the thin line, a line, which means absolute freedom to them. This film attempts to find out the unique feelings up there in the sky, in a space, which otherwise is only reserved for birds.
