Here varius generations with a passion for alpinism have written in different ways, but with identical enthusiasm, the story of these pinnacles and towers. The film ends with Marco Anghileri who interprets an original and ideal way of linking together thesebeautiful mountain routes, marked by the course of the sun, from dawn to dusk.
