The conflicts and the joys of each member of the Kervelec family reveal the complexities of inter generational relationships, from grandparents to grandchildren.

After his mother has an accident, obese Julien (14) is taken in by his uncle's family in Switzerland. The family, who to all appearances are totally "normal", make Julien's nutrition and well-being their highest priority. But then Julien falls in love with Keiko, a young Japanese girl. In order to seduce her he pretends to be a Sumo-champion but soon finds himself in a quandary: he needs to lose weight for his new family, but he needs to gain weight if he is going to take part in the Sumo training and seduce Keiko. Bit by bit Julien's lies start to crumble and it becomes very apparent that the other protagonists' notion of normality is very relative.

Sabine's concern is all the more acute when she learns that the Izieu roundup cannot be included in the trial of the former Nazi, for lack of evidence. Sabine fights so that the children of Izieu are not permanently forgotten by history.
