At first sight, 10-year-old Benoît Brisefer, seems like any other little boy his age. However, Benoît is endowed with amazing force. All the bandits who cross his path learn this to their own cost. But, unfortunately, no one is perfect... As soon as he catches a cold, Benoît loses his extraordinary physical abilities. Hence he never takes off the woollen scarf wrapped around his neck. Brave and very determined, he doesn't hesitate a second to take action to defend his friends. So, when Poilonez - a well known crook - and his gang decide to focus on Mr. Dussiflard, his taxi driver friend, Benoît does all that he can to thwart his plans.
One stormy evening in 1829, the aging writer René de Chateaubriand, takes refuge in a mountain retreat at Cauterets, a small town in the Pyrenees. Here, he meets Léontine de Villeneuve, an aristocratic woman forty years his junior, who ignites his passion and who seems to be as equally attracted to him. Under the watchful gaze of the maître d'hôtel, Chateaubriand embarks on what will be his last great love affair, with a woman he will later refer to in his writings as L'Occitanienne.
