Les Routes de l'impossible (2007) : 20x2

Deep in the frozen Altai Mountains of western Mongolia, a nomadic family prepares to face the year’s most perilous challenge: a 120-kilometer migration through snow, bitter cold, and storms. To save their herds from starvation, Bazarbay, Talap, and their relatives must drive nearly 200 animals to their summer pastures. Among them is 7-year-old Daryn, embarking on his first great journey. Devastated after the sale of his beloved horse, the young boy is given a mission by his father: to look after "Doudou"—a frail young calf—and a goat about to give birth. It is a responsibility that will force him to grow up faster than expected.
