Four cars burn in the parking lot of Anne Frank College; the situation is unsustainable: if it persists, parents will take their children out of the center, which could lead to the closure of the school; Ester, the director, goes to Hugo.

Hugo has to identify the group of nine students he considers responsible for all the ills of the center; to apply his method, Hugo first needs to convince the parents of the boys and girls to sign the authorization.

The first step to treat a disease is to make a good diagnosis.

Nassir, Nourdin’s father, works in the garbage dump. They don’t get along very well, and Nassir wants his son to work with him. Nourdin, however, isn’t too excited about the idea. Quite the contrary: he thinks the job is disgusting. If he doesn’t want to end up like his father, Nourdin should start studying, stop thinking so much about his muscles and start thinking about his brain, something that is almost impossible for him. In the back of his head there is something that is causing a lot of noise and is preventing him from thinking clearly. Something that he experienced in a camp when he was just a child.

The school year is going by fast, and the teenagers seem to be making progress. But the job is so demanding that Hugo’s weariness and frustration keeps growing. Every day he has to deal with the distrust of some of the teachers towards him, with Ester’s debatable support, and with the complaints of some of the parents. Silvia’s parents, specifically, who have filed a report against Hugo with the Board of Education after seeing their daughter hurting herself. Despite the threats, Hugo is growing closer to the students and wants to get into their private space. And there is nothing more private than sex. When the teenagers are opening up and being completely honest, Mari Cruz, the Assistant Director of Education, barges into the school and temporarily cancels Hugo’s classes. Hugo doesn’t understand Ester’s fearful behavior, and he revolts. Facing the possibility of having his method shut down by the Assistant Director of Education, HIT decides to give one last special class, with very special guests.

Hugo quit his job at the school after the incident with the Board of Education. He thinks he did it out of dignity, but it is actually his fear of failure what made him take the easy way out and run away. The problem is that his decision has the worst of outcomes: alcohol. After 18 months sober, Hugo falls back into drinking. On his way down to hell, Hugo makes an unlikely travelling companion: Erika, who has also gone too far with drugs. Through the night, they will accompany each other, and Hugo will realize that he can’t give up on the kids now. The anger he feels towards the Board or the very system is no reason to abandon the group overnight. Hugo decides to go back to the school and continue applying his method.
