One snowy day, in the heart of high altitude reserves, 5 fox cubs are born into a rocky chaotic world. Whereas they share the first careless months of their lives with the chamois, groundhogs and ibexes, comes the end of summer, tensions are heightened. Not all of them can remain here. From now on, their lives will be a series of trials, with some of them remaining within the clan and others living a nomadic life in search of territory. How will they contend with the golden eagle and the return of a pack of wolves? Will they tolerate the wandering fox that impinges on their territory? Sometimes touching and forever full of surprises, this film, shot in its entirety with freely roaming wild animals, reveals the extraordinary capacity of these foxes to adapt to high altitudes.
