Tina is head of education at the Marie-Labrecque school that offers a free education to pregnant teenagers. The students have to undertake to complete their secondary school studies. Accompanied by Françoise, the school nurse, she welcomes a newcomer, Edwidge.

In the Pelletier household, the ambiance is particularly heavy as Anne-Sophie, Anaïs' sister, tells her father a few home truths. Feeling an immense weight on her shoulders, Josée heads to Montreal to find a solution for Anaïs, who doesn't want to return home.

Tina and Christophe try to convince Jolène, a particularly bright student, to pay more attention to the way she dresses. Christophe notices that Edwidge suffers from panic attacks. Luc informs Tommy that he can no longer use the company car as long as he's in a relationship with Anaïs.

The school's funding is under threat. It's Camille's birthday, with Edwidge's help Nico has made a cake for her. Still undecided about what to do next, Anaïs suggests to Tommy that he returns home for the moment.

Due to the lack of candidates, Tina has to accept the idea of taking-on a male night-watchman. She discusses the decision with Christophe. Flora has a visit from her friend David-Étienne, who had promised to marry her.

Tina reminds Christophe that the school doesn't yet have the right to provide accommodation for Anaïs, but he's determined to do all he can to help her. Edwidge's aunt comes to the school in order to explain to Edwidge the truth about her parents' death.

Tina redoubles her efforts to try to cheer up Edwidge. Anaïs is delighted to finally be accepted by the school, whilst the gulf continues to widen between her parents. Tina has accepted Christophe's invitation to dinner, who make the most of the occasion to reveal more about his past.

Christophe, David-Étienne and Flora's parents meet up at the hospital where their daughter has been admitted. The friends at Marie-Labrecque wait feverishly for news. Tina encourages Anaïs not to burn all her bridges with her sister Anne-Sophie.

Tina summons Anaïs and Den in the hope of settling their dispute. Christophe takes time to listen to Rodge who is more and more at a loss about which side he should take. The gulf widens between Tommy and his father concerning Anaïs.

Everyone is worried about Flora's disappearance. Den immediately imagines the worst, whilst Edwidge reacts very emotionally. Jolène, who didn't return to school at the appointed time, has to explain herself.

Françoise gives a sex education lesson that interests the girls. Alerted by Jolène, Christophe tries to persuade Den to talk to him about his relationship with pornography. Tina visits her parents to ask for their help in finding her biological mother.

Tina explains to Christophe why Edwidge's case affects her so much, as the all-important day approaches for the latter. Anaïs feels very much alone and the news from home doesn't offer much comfort.

Quentin asks Christophe if he can see Edwidge. Morgane tries to make Flora understand the importance of making a real effort with her schoolwork. Tina admits to Christophe that she still feels uncomfortable with Edwidge's choice. She accompanies Anaïs to her first scan.

Caught up in the whirlwind of her emotions, Flora is neglecting her schoolwork and has every chance of failing her year. Tina tries to make her see reason. Den wonders about her new boyfriend who doesn't seem very interested in sex and talks to Christophe about it.

Edwidge prepares to leave the school to live in sheltered accommodation. She warmly thanks Christophe before enjoying a final dinner with the girls and staff. Whilst continuing to sign-up potential sponsors for Tina, her father remains tormented by her insistence on finding her mother.

Flora prepares to return to live with her parents. Den gets to know Bruno, who has a somewhat unusual lifestyle. Christophe, worried that she's heading into a toxic relationship, makes an even greater effort to keep in touch with her.

As Den's due date approaches, Françoise notices once again the extent to which the young woman has a ruthless attitude towards her body. Tina and Christophe worry about her and have every intention of keeping a close eye on her.

Tina tells Christophe that Camille's emancipation request will be heard shortly. They still haven't managed to contact her mother. Tina invites Jolène to recount her story to businesswomen susceptible to help the school.

Den, who has gone back to the chaos of life with her family, asks Tina to take the necessary steps so that she can return to the school whilst waiting for sheltered accommodation. The legal decision concerning her request for emancipation is explained to Camille.

The all-important day is just around the corner for several students. Tina makes even more effort to try to contact Camille's parents, who's very insistent that her father must be present. Thomas comes to Montreal to be with Anaïs.

Christophe tries to encourage Tina, thoroughly shaken up by all that's happening in her life. Julie's lawyer pays an unannounced visit to the school to plead her cause. Camille with her baby and her father call in to say hi to Tina.
