It focuses on Sofía, a six-year-old girl who apparently suffers from serious adjustment problems and rebellion due to the overprotective behavior of her mother, Mariana. The second story focuses on Natalia, a teenager who can't remember whether or not she had sex with Mateo, a shy classmate, on a drunken night. In the background, the development of a relationship between Andrés, the psychologist in charge of the School Guidance Office, and Paula, the school principal, is revealed between the lines.

Andrés interviews Natalia, and then Mateo, trying to find out if they really had sex, while receiving an invitation from Paula to see a play that a teacher wants to show to her students, and then she asks him for help finding a psychologist to treat her, since she has started the procedures for her divorce.

Andrés consults his supervisor about the helplessness he feels, the lack of passion he feels about his work, and a recent dream in which he saw himself and Paula paralyzed at school. Paula and Andrés call Natalia's parents to discuss their daughter's conflicts with her classmates, but he doesn't dare tell them about her doubts about whether or not she had sex with her classmate. Orsori, a music teacher, comes to Andrés, exhausted by his failure as a teacher and his inability to impose respect and order in the classroom. He suggests writing a letter to each of his students, so he can express what he can't say to them. Later, Andrés meets with Paula, and they talk about the theater trip they had the night before.

Andrés organizes a shared session between Mateo and Natalia (who previously mentioned that she visited the gynecologist and confirmed she's still a virgin), where he suggests that each of them write down what they'd like to say to the other and then read it. He concludes that, while she doesn't deserve to be insulted and mocked by her classmates, she often has impulsive attitudes that are selfish or unconscious of others.

Andrés speaks in his office with Juana, a fifth-grade student they find sitting on the rooftop of the house next to the school. She doesn't have the money to go on the senior trip , but she doesn't have enough of a relationship with her classmates to feel bad about it. Her family also doesn't have the money to pay for the trip, and her classmates decide to give the free ticket to another girl.

Andrés welcomes Juana, who cut her wrist in class, into his office and talks with him about her poor relationship with her teachers, the relationship between her divorced parents, who wouldn't pay for her graduation trip, and the argument with her friend Tuti that may have prompted her decision. Finally, he suggests she should start therapy to determine whether the cut was an accident or a suicide attempt.

Paula asks Andrés to help Santiago, a student with Asperger's who hasn't been in his classroom for two days and instead wanders the halls. Santiago is very intelligent, obsessive, and rational, and explains that he doesn't want to go to class because a classmate told him he has "a dead body in the closet," and he can't interpret metaphors . Meanwhile, Juana arrives at the office to deliver something to him, and Andrés has to kick her out for interrupting him and causing Santiago to have a meltdown by wearing purple clothes. Later, when he manages to dissuade Santiago from calling the police and listens to the full story to explain what really happened, he gets him to return to the classroom.
