Forty year-old Bruno Ledeux, seen sitting across from the doctor, gives the impression of a man who is no longer young but not yet old.Condemned to remain nothing more than a son, he begins his downward slide, as if a fog had shut him in a cage from which there is no escape. Bruno can never have children .He says nothing about this diagnosis to Anne, his beloved wife. Nor does he tell her about a large debt he has taken out. It is as if Bruno were a man without any qualities or talents. A mediocre man who has lost all pride. Though now everything appears hazy in his memory. Like a river that flows peacefully, showing no signs of the hidden currents at work below. But at times those currents can return to the surface. Without warning.

Il quarantenne Bruno Ledeux ha appena saputo che non potrà mai avere figli e ha contratto un debito difficilmente estinguibile con un usuraio. La moglie Anne non può far altro che assistere al suo lento scivolare nella depressione. Fin quando un giorno l'usuraio scompare. Tutto dovrebbe volgere per il meglio senonché il figlio del suo persecutore, Luca, fa in modo di incontrarlo e inizia a pedinarlo.
