Natalia– a prima ballerina at the Mariinsky Theatre, is preparing to dance in the premiere production of «The Four Seasons». The ballet was staged by her husband Sergei, who suspects his wife of cheating with her partner - the imposing Italian ballet dancer Francesco. There are only 4 days left before the premiere, and the atmosphere, both in the theater and in Natalia's personal life, is heating up: the troupe members are writing a collective letter against her, and Sergei is removing her from the premiere. But Natalia finds the strength to resist.
