Victoire has just been transferred to a new high school in Angoulême. She becomes a senior education advisor and fits perfectly into her new professional environment.

Three months after her appointment, the class council arrives: it is already going very badly, as many are opposed to Victoire's methods of education. While in the middle of the council, a dispute between two girls and a boy takes place, Victoire has to face several dangers within the school: pornography, drugs and family problems.

But she is without the support of Valéria, her best friend, and Emma, her daughter.
