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.

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.

Jolène prepares to meet a boy that she has so far only contacted online. Tommy has come to join Anaïs in Montreal. They both pay a visit to the Marie-Labrecque school where Tina and Christophe give them the attention they need, but their situation is far from simple.

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 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 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.
