On December 31, 1979, five students come to a sanatorium lost in the Karelian forests to prepare for the New Year's spectacle. They are led by a teacher and the rector's daughter Mymra. The athlete Pasha is preparing to propose to his girlfriend Katya, but the teacher, who is in love, kidnaps her. Mymra, who has long been jealous of young Katerina's teacher, arranges a romantic seduction for the teacher. In the middle of a disco party by the pool, local driver Vitya intervenes in the students' amusement, an expelled student from the history department who considers himself descendants of the Karelian shamans. He performs a bloody ceremony, but he errs in choosing the victim.
