The story of a 1,100 km winter expedition to Alaska, the last stage of an adventure that has led Maurizio Belli, from Trentino, to follow the routes of the Gold Rush over a period of 25 years, first alone and then with his friend Fulvio Giovannini. On foot, by bicycle, by canoe and on skis, the scope is not to achieve a new record, but to trace a personal path. The two adventurers now take on their most daring challenge: on skis, sleeping in a tent for 55 days on a river of ice, following their childhood dreams.
