Barriola is one of the shrewdest and most cunning foxes in the mountains, especially when unwary pass by with bags to steal. He lives in the company of the charcoal burners of Aizkorri, raiding the paths and keeping a close eye on the local vulture. But these are not his only worries, as it seems that Barriola has fallen in love with a little hen named Graziana. Overnight, the mayor of Segura proposes to the charcoal burners that they leave the area, although there are dubious municipal interests behind it.
