With original images and interviews, the documentary recounts environmental and sociological matters linked to the reappearance of wolves in the Alps, after they had disappeared for almost a century. Not everyone is happy, especially among those living and working in the mountains. The story is recounted with a simple and immediate language, to describe a fascinating animal and its precarious coexistence with man in an increasingly domesticated landscape where livestock graze. The events are organised into chapters, concluding with the hope that the right balance will be found between man and one of his great antagonists.
