Ninth-grader Nikola, along with her younger sister Aneta and their father, are moving to a new city. This means changing schools and finding new friends. Nikola is starting ninth grade in an unfamiliar environment where she has to earn her place. However, it is not easy for her, because the girls are led by Majda, who resents the fact that the class idol Šimon has begun to discreetly eye the new student.
