Schoolgirl Masha and her parents are forced to move from Moscow to Novomorsk. After the elite gymnasium on Rublevka, it is not easy for a girl to put up with the rules of a provincial school. At the new school, she becomes a victim of bullying - sophisticated psychological and physical harassment by classmates. It becomes especially harsh because of Masha's feelings for Kris's boyfriend, the main star and rebel of the school. With the filing of Kris, the nickname "Crybaby" stuck to Masha. To cope with problems and tears, the heroine is helped only by music and a group that she has gathered together with other students.
