After 20 years away, Isabelle, a former climbing champion, returns to her village in the Alps for the funeral of her mountain-guide father. She decides to open up a new climbing route with the help of Kenza, her protégé - something she'd planned to do with her father. But the past and its secrets resurface through Antoine, a brilliant mountaineer who was Isabelle's first love.
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.
