The filmmakers find the Abruzzo National Park to be the most suitable place in Europe to film the wild fox, one of the most elusive and fearful animals in the forest, with its proverbial cunning that allows it to escape all the traps set by man. For five months, the documentary filmmaker and his assistants live in these forests, observing the landscape and its inhabitants: deer, bears, wolves, wild boars, and roe deer. They manage to gain the trust of a female fox, accompanying her, waiting for her, losing her, and finding her again.
