Alma and Yoli, meanwhile, are still the most veteran of the Zurbarán and will not let themselves be trampled by them so easily. Meanwhile, the boys are dedicated to showing who is the strongest in the school. Jon, after the accident he suffered, also returns with a desire for revenge, since he has spent the whole summer in a coma. When you wake up you will only want to remember the good things that were in your life before, among them, your girlfriend Daniela or your friend Salva. However, things have changed in these months. As for the teachers, they will join forces against Enrique, the new director of the school, who does not mince words and is a strictly correct and orderly man. His first rules will raise blisters among students and teachers will not know how to stop him. The only way to do that is by joining the students, and Yoli could be an exemplary student representative. Finally, Xavi, the new art teacher, will arrive covering Jorge's absence, who will not return to school after breaking his relationship with Verónica this summer. Now the teacher will only want a little peace at home, however, this will be truncated when Vaquero sneaks his wife Sara into the house, a very pretty and uninhibited girl who will give him more than one headache.

Verónica is very concerned about Teresa's crazy attitude. Xavi promises to help him, and although his intentions are good, his manners are not the best, especially when he meets the girl in class with enough students with whom he has hooked up to make her see that his attitude is going beyond promiscuity. The girl, totally offended, will talk to Enrique to take action. Meanwhile, Sara will be more subtle in making her see that a certain goal is worth more than a thousand wrong ones, the girl will stare at Roman, the attraction is clear. For their part, David and Fer discover how difficult it is to make ends meet, they need work, but things are very difficult. David has an opportunity from heaven when he meets Susana, his ex-girlfriend, who offers to work in her hairdresser in exchange for his closeness, and the girl always had David very present and now he will not dare to tell her openly that he is homosexual. On the other hand, the two of them will not be the only ones who have problems with the house when Román receives a call from Clara saying that he needs to sell the house. Roman will offer to pay half of the couple's rent in exchange for a room.

Yoli has managed to be the Zurbarán student delegate on her own merits, but Daniela is not going to make it easy for her. Taking advantage of his friendship with Enrique, he manages to take charge of a school newspaper from which Daniela hopes to control her classmates and take revenge for Yoli's electoral victory. But the hardest hit will be Salva, the center of Jon's wrath and Zurbarán's new group of baddies. Instigated by Álvaro, Jon will fight Salva for the position of graphic humorist in the newspaper, and he will do it by giving him where it hurts the most. The newspaper will also be the center of the hurricane for Sara and Verónica. The literature teacher does not finish swallowing her new roommate, but she will have to join her in organizing the new after school activity. Meanwhile, Xavi is not satisfied with one being able to have them at both, and uses a portrait contest as an excuse to get closer to Verónica, while continuing his relationship with Sara. Both feel special because of the attentions of the artist, but secrets are not easy to keep in the teachers' homes, and the truth will come out in an embarrassing way for all three. The differences between Olimpia and Enrique are accentuated with the appearance of Peque, a gypsy student who wants to fight against the stereotype and study to carve out a future for herself. What for Olimpia is an example of determination, for Enrique is nothing more than an opportunity to promote the educational excellence of the school. The director again imposes his criteria, but it will be Peque who pays the consequences.

David's dreams with his ex-girlfriend continue, although he doesn't dare to tell Fer anything. However, he knows it, but exactly the same thing happens to him as David: he has no idea how to deal with the problem. Fortunately, they have Yoli to give them a hand and find out if David is feeling something for his ex again or is something different. The couple once again face an obstacle of unknown consequences. Jon has been crowned as the most charismatic of the Zurbarán students thanks to his alter ego in the newspaper "The Devil on Wheels" and his fans are multiplying. Álvaro can't help but look at him with some envy despite being Jon's friend. This will lead him to try to prove to everyone that he can be as tough as Jon or more. On the other hand, Teresa, despite her new status together with Daniela, still has a pending account with Alma that she wants to settle. He decides to attack her head-on, but Alma is not an easy enemy, and she easily escapes from each Teresa's onslaught. But Alma is more concerned about leaving behind her flirtation with prostitution that has made her money enough to go to the United States. Has everything under control as long as someone does not remove the matter. Someone like Teresa. In class, Verónica, fed up with her students' spelling mistakes, decides to suspend everyone who makes them. This generates a conflict between teachers and students, in which Yoli will have to put her talent as a delegate to the test to agree with all her classmates in what they consider an injustice. But Verónica also has other problems in her head. Coexistence in the apartment with Xavi and Sara has been complicated after the incidents of the previous chapter. While trying to make peace, he discovers that Xavi and Sara are continuing their adventure. Annoyed, she turns to Vaquero to separate the couple. After all, Verónica is interested in Xavi and Vaquero is interested in Sara. The challenge for Verónica will be not to betray her new philosophy of doing things calmly, and not like crazy. At the same time, Olimpia blames Enrique that Peque, Zurbarán's new gypsy student, has dropped out of school. Enrique denies any responsibility, considering that he did what he had to do. Olimpia sets herself the challenge of getting Peque back to class and teaching Enrique a lesson.

Jon and Álvaro's group continues to be the most feared in Zurbarán. They do not pass one or the members of his gang, especially Toño, a timid student who does not allow himself to be helped by his parents or teachers. His life is a hell in which he lives locked up by his own decision, and in which Jon and Álvaro, his supposed friends, are in his opinion the culprits. This will lead him to make a decision that will make all the plots converge in a frenetic and harrowing adventure in which everything will be put in danger for each and every one of the characters. Everything including their own lives. The separation of Fer and David seems to have no going back. At least that's what Fer deduces from seeing that David has accepted her with complete resignation. And this, as he confesses to his friends, annoys him a lot. So if you are not sure, you will have to be the one to take the step to try again. However, this time it is David who is not willing to put up with any more indecisions. In turn, Teresa is very taken aback by the discovery that Alma works in a hostess club. In his campaign to get back on track, he doesn't want to share this information with Daniela, but he doesn't know what to do with her either. Tired of Román not trusting that he wants to change, he tells him what happened with Alma so that he understands why he has not asked for forgiveness. Yet someone else finds out just the person who loved Alma the most: Álvaro. Teresa also wants to fix things with her mother, but that doesn't seem easy either. Verónica, after having slept with Xavi, is not willing to share it with Sara. This obsession will lead her to leave her daughter aside and confront Sara in a disproportionate way. It will not take long for you to realize that behind all this are your personal demons, you have an unresolved past that can lead you to lose the things that really matter. Meanwhile, Olimpia is beginning to discover the more human side of Enrique after he recognized that the effort he made to recover Peque for school gave him a lesson. He's definitely starting to like it. But he still has to discover the detail that will show the most tender Enrique, even if this generates a new conflict.

One of the first consequences is the measure adopted by Enrique to definitively solve the Zurbarán's security. The principal has decided to install surveillance cameras and a metal detector at the school. The measure causes the outrage of students and teachers, who are not willing to be controlled or lose their right to privacy. Alma, Salva and Román lead the opposition to Enrique's measures trying to boycott camera surveillance by all means. After what happened, Jon and Álvaro have become the "sick" of the school. Jon feels very guilty and wants to earn people's forgiveness. Instead, Álvaro prefers to escape his deepest feelings by pounding his body in the gym and discarding any attempt to apologize to anyone. This difference in attitudes will cause a confrontation between the two. Yoli and David suffer the loss of Fer very differently. On the one hand, Yoli tries to hold onto the memory of Fer obsessively. It has been proposed that no one forget him and, for that very reason, he is in charge of organizing a tribute in his memory at the school. On the other hand, David tries to continue with his life, something that is impossible since Yoli constantly tries to remind him of Fer's presence. Besides, Yoli controls David's life obsessively, as if Fer continues to remain among them. A situation that will be about to end their friendship. Alma continues to work at the Rodeo Bar, something that may change soon, when she discovers that one of the clients is an acquaintance ... more specifically, a professor at Zurbarán. Teresa and Román feel more and more attracted to each other. But Teresa does not finish letting herself be carried away by her feelings. In addition, Daniela, who does not see the rapprochement between the two as good, will not stop discrediting Roman and judging Teresa's desire. After having been absent for two months, Verónica rejoins the classes. But going back to the classroom is not going to be easy for her, since Verónica continues to suffer the aftermath of post-traumatic shock. With the help of Arturo, he will try to overcome the panic caused by entering the school again. Xavi and Sara have formalized their relationship in recent months, but doubts about his decision begin to assail the teacher and he begins to neglect his relationship with her. Sara, who is not willing to allow anyone to sit her down, especially if it is a romantic dinner, decides to take drastic measures: find a replacement.

Daniela's thirst for revenge after Teresa's rudeness for Román, will lead her to want to do the greatest possible damage to the couple. And for that he will decide to play his best trick: the tape that he stole from Verónica. But things take an unexpected turn, when Daniela accidentally discovers that Enrique has finally bought the school and plans to tear it down to use the grounds. A fact that will take place in two weeks if nobody prevents it. Daniela will immediately sound the alarm and all Zurbarán will mobilize against Enrique, with Yoli and Olimpia at the helm. The latter, who believed that she had finally managed to get closer to him, will take it personally and, with Sara's help, will propose a general strike that will affect both students and teachers. All the protagonists will decide to stay to sleep in the Zurbarán to increase the pressure towards Enrique, since he will try by all means that the strike is not public so that his buyer does not back down. Sara will be one of the main leaders of the strike, something that will distance her even more from Xavi, who does not share his girlfriend's revolutionary impulses. The gap will become untenable for both of them, and they will finally end up admitting that who they want to be with is with Vaquero and Verónica respectively. But things will not be easy, Verónica does not seem to be very busy starting a relationship and for Sara things will get even more complicated when immigration agents discover that her marriage is a sham and decide to deport her to Argentina. The situation between David and Jon will remain red hot, and having to share space 24 hours a day will not make it any easier. Jon will end up making a desperate decision to get his forgiveness even if doing so endangers his physical integrity. Things will not be easy for Álvaro either, he will decide to get Alma out of prostitution at all costs, even if it means doing a lot of damage to the person he loves the most. On the other hand, Teresa and Román will get closer and closer, and it will be Román's new job as a photographer, which will finally make them both confess what they feel for each other. In this race against time to save Zurbarán, all conflicts will break out one by one, leading the protagonists to make drastic decisions that will affect their future forever.
