In "Polina," Bastien Vivès once again surprises with his choice of an unusual subject: with a vital, precise line, he depicts a tender yet unflinching portrait of classical ballet, focusing on the delicate relationship between master and student. The talent of the young ballerina Polina Oulinov shines brightly, attracting the attention of Nikita Bojinski, one of the most admired yet feared masters of contemporary dance. Under his guidance, Polina evolves into a successful artist who, despite rigorous training and a life full of constraints, is determined to maintain her independence.
