Vodoley Studio

On December 31, 1979, five students come to a sanatorium lost in the Karelian forests to prepare for the New Year's performance. They are led by Associate Professor and the rector's daughter Mymra. Athlete Pasha is going to propose to his girlfriend Katya, but the Associate Professor, who is in love, kidnaps her. Mymra, who has long been jealous of the Associate Professor for young Katerina, arranges a romantic seduction for the Associate Professor. In the midst of a disco party by the pool, the local stoker Vitya intervenes in the fun of the students, an expelled student of the history department who considers himself the descendants of Karelian shamans. He performs a bloody rite, but is mistaken in choosing a victim.

Atakan is a bloody boulder, a giant granite block, on which pagans sacrificed human sacrifices for centuries. A group of student historians, led by a young teacher, descend into the dungeons of St. Petersburg to find the legendary stone. With each step, the situation gets out of control, only death awaits them. The attack craves new blood. Who will survive?
