Othilie spends her vacations with her uncle Antoine, an old lonesome bear. In charge of a regional park, Antoine lives a long way from Paris, in company of the shepherd Tambourin, whose frightening face hides the innocence of a new-born child. Since the arrival of Othilie, odd things happen. A slaughtered sheep is found and weird howls are sounding through the night. The wolves are not far away.

One day, you receive a present. And then another. And on and on. Till the present isn't a present anymore. It's a nightmare. And all because YOU are not Ivan Gallatin.
