School

9 "A" was an exemplary class, with their teacher being Nosov Anatoly Germanovich, a strong and experienced educator who was named Teacher of the Year in 2009. Following his sudden illness, the class is left without his guiding presence, and the image of the exemplary class begins to fade, with discipline deteriorating. Anya Nosova, the teacher's granddaughter, is considered one of the most difficult students in the school. The arrival of new student Ilya Epifanov leads to situations that reveal unexpected sides of the students, disrupting the usual dynamics between classmates and teachers. None of the teachers are willing to take over the class, which has transformed from a model class into one of the most challenging.
