In the spring of 2006, the world's only example of a white ibex was sighted in the Les Laure valley in the Aosta Valley. Two men, only apparently very different, are on the animal's trail. One is Mauro Buvet, an alpine hunter who, in his passion for hunting and search for the lost harmony between man and nature, follows the ancient rules of not killing this rare animal. The other is Alessandro Mosca, a veterinarian studying the ibex, which is at a high risk of extinction because of its genetic patrimony.<%YOUTUBE=IX0VQQkSBb4&noredirect=1%>
