Oleg is a high school student who, together with his friends, engages in petty theft. Olga is the daughter of a military man who controls her every move.
A very strange teacher appears at school, who instead of a lesson topic tells the students 3 stories. These are modern interpretations of the legends about Onar, Irga and Chotkar - the heroes of the Mari people, "the last pagans of Europe". However, the head teacher of the school begins to suspect something is wrong.
