1977, in a small village in Ticino: Mario, 16, stands on the threshold between adolescence and adulthood. At school and in life, many things seem to slip through his fingers, and tensions with his father are frequent. Sent to a mountain farm for the summer, he discovers a wild and liberating world where nature sets its own pace. Up there, everything seems possible: the beauty of the landscapes, the warmth of new encounters, and the awakening of a first love transform the way he sees the world.
