While the judge was about to deliberate on Guilhem's custody, the child ran away. To find where he is hiding, Louison tries to put himself in his place.

Louison wants to resume his studies in meteorology. To become popular, Houcine and Guilhem distribute alcohol in the college toilets.

Louison agrees to a meeting with Ariane. Unfortunately, this coincides with the day she has to accompany Guilhem incognito to the swimming pool.

Louison participates in Lemonial's parenting course. Léna gets closer to Guilhem, who is afraid that this will jeopardize his reconciliation with Houcine.

Louison struggles to get Guilhem to stop being angry with him. The disappearance of Mrs. Grassin's dog could be the key to her reconciliation with him.

Houcine leaves Guilhem for Léna. Guilhem's diagnosis is confirmed. He hides in silence. Louison and Reza will have to get him out.

While Louison plans to get back together with Reza, her ex-husband, Houcine asks Guilhem to help him seduce Léna. To achieve this, the two comrades resort to voodoo...

Louison goes all out for Guilhem's birthday party. The objective is clear: to prove to Lemonial that she is offering her son a healthy social life.

A social investigation begins to determine if Louison can retain custody of Guilhem. She will have to check all the criteria listed by the investigator.

It's the start of 6th grade for Guilhem. Because he hurt a comrade, he must consult a psychologist. The diagnosis is clear: Guilhem is autistic.
