After spending four months in jail, Teresa is declared innocent of the murder of her own father and is released from prison, but the teacher is not the same as before: she is exhausted after her time in prison and has no strength to face her relationship with Roberta, his sister.

Teresa moves to a little house in Seville and gives Carmen, the new administrator, her room. Carmen’s first attempt at trimming the budget does not go over well with the students.

The Academy prepares for a visit from the actor Benito Padilla, Manuela's cousin, and the director Jorge Merlot. Meanwhile, Roberta tries to get closer to Teresa and Carmen continues to pass information about the Academy to the Peraltas.

Since Teresa has returned, neither students nor teachers understand her. Roberta tries to go to Teresa for help, but she is distracted by Ines. Meanwhile, the girls propose that the Academy's street name be changed to that of a woman.

Carnival is approaching and everyone begins to prepare enthusiastically for the event at the Academy. Meanwhile, Teresa still doesn't know how to approach Roberta and Flavia is torn up over her pregnancy.

The archery competition is approaching and the competitors from Madrid arrive at the academy. To everyone's surprise, Angela is accompanying them. Flavia visits the doctor. Teresa and Roberta try to adapt to their new relationship.

Upset with Vicente, Luisa receives an unexpected visit: her son, Arcadio, and Catalina, his fiancée – a lady Luisa’s age. Arcadio wants to reconcile with his mother and make up for lost time, but the science teacher doesn't know what to think or do about it.

The Academy closes its doors and Manuela feels terribly powerless. The Peraltas claim the school as theirs and have the documents to confirm it. Teresa, however, will not let Manuela sink with the school.
