The race to Varna is on. Six candidates will be selected and trained by Diane to represent the Opera de Paris in Bulgaria. Zoe works at a crazy pace imposed by Diane, but unfortunately a serious injury sends her to the hospital.

In a physiotherapy centre, Zoe works hard on her comeback. Eager to return, she ignores the doctors' advice and pushes herself too hard. At the opera, Flora and the other candidates are struggling with the strenuous training.

A new season is beginning at the Opera. Zoe is the prima ballerina, Flora is part of the corps de ballet and the position of the dance director remains vacant. In addition, the company welcomes ballet mistress Diane Taillandier.

Backed by the younger generation, Flora and Aurore continue their crusade against their dance director, and write a manifesto to be signed.

Flora and Aurore are ready for revolution. They break the law of silence and tell Nadia Menour, the opera's director, about Diane's abusive techniques. Zoe, however, steers clear as she remains loyal to Diane.

After the official announcement of her dismissal, a strike call was launched in support of Zoe. Flora supports the movement, but when called to replace striking dancers, she cannot refuse this opportunity to go on stage.

Jonas prepares to go on stage for the last time to say goodbye; the company receives a visit from the Bolshoi.

Zoe receives some advice from lawyer Maître Delva; Sébastien must convince a frustrated dancer to stay at the Opera, while managing the whims of a choreographer.

When several dancers are stricken with food poisoning, Sébastien takes advantage of the situation and offers Zoe the lead role in Swan Lake, being certain that she will be forced to refuse. However, Zoe takes up the challenge.

Flora is searched by the police and is found to be carrying drugs; Zoe makes an unexpected sacrifice.
