A story about departure and return - and what makes a fulfilled life. As children, Pietro and Bruno boldly explore the abandoned houses of the mountain village, wandering through shady valleys on endless summer days and following the wild brook to its source. As adults, the paths of the two friends diverge: one never leaves the village and tries to revive his uncle's cheese factory, while the other is drawn out into the wide world, magically attracted by ever higher peaks. The invisible bond between them brings Pietro back home time and again, but they no longer agree on where to find the happiness of life. Can their friendship endure despite this?.
