Schoolgirl Masha and her parents are forced to move from Moscow to Novoorsk. After the elite gymnasium on Rublevka, it is not easy for a girl to put up with the rules of a provincial school. At her 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 Chris's boyfriend, the main star and rebel of the school. At the suggestion of Chris, the nickname "Crybaby" was glued to Masha. To cope with problems and tears, the heroine is helped only by music and a band that she has put together with other students.

For the first time in a long while, the father shows up at the kindergarten and, together with his son, turns a game of hide-and-seek from the teacher into a fantasy adventure—spinning tales of dragons, portals, and magical worlds. When the mother arrives, the father tries to explain himself, but his words no longer hold any weight with her. Resigned, he asks for five minutes to say goodbye and tells his son he must fly off to another world for twenty years to preserve their magic. In the boy’s memory, his father transforms into a massive dragon—soaring up to the ceiling and flying away through a drawn door. All that remains is a toy: a plastic dragon with a broken wing.
