Sacha starts her first day of high school in a new school. Her arrival during the year hides a secret that she must keep, especially when she meets a new gang who press her with questions.

Sasha tries to settle in with his new friends, who are giving him a hard time. This is no easy task, especially when Anna decides to invite him to her birthday party, to which only a few are called.

After the birthday party, Sasha and Pauline are at each other's throats. The situation escalates when Anna decides to invite herself to sleep over at Sasha's house, risking her secret. Nothing goes according to plan.

Sasha wants to undergo a medical procedure that will solve their problem. But her parents are not happy with his decision. This is made more problematic by the fact that the doctor who is treating Sasha is vehemently opposed to her decision.

Sasha has finally found her stride with the gang. She even starts to get closer to Alex. However, she forgets that Pauline especially needs her on the eve of her figure skating competition.

Sasha makes a big mistake that puts her health at risk, but she refuses to talk about it to anyone, least of all Alex, who has just invited her to study at his place.
