Adriana is flabbergasted when she discovers the misdeeds of her former mentor and his role in Zoé's suicide. Jeff and Angèle go back on the track of the counterfeit bottle, but tear themselves apart about their future. While at Le Ballast, the star Adriana dreams of has never seemed so close, she discovers the disappearance of her sister Stella.

Increasingly at risk for Arinov and his coke business, Adriana, Stella and the Rubens are determined to get rid of the mafia. To finance their offensive against Arinov, Adriana must return to her roots in Meaux and set up new traffic there. Another threat: the counterfeit bottle bought by Vatine, who risks discovering the deception if they don't get it back on time.

To make them pay for their prank, Arinov demands an additional tribute of €200,000 from the Rubens and Adriana each week. Inspired by the restaurant's expensive wine list, Jeff and Angèle set up a traffic of fine wines, whose flavors Adriana helps them replicate. But just as their plan is about to bear fruit, a new request from the Russian mobster forces them.

Adriana reopens Le Ballast, but faces the machinations of Angèle and Jeff who need the restaurant to launder Anton Arinov's money and settle their debt. Stuck by the Russian mafia, they try to find a new patron within the Armenian mafia, through Stella. But Adriana is in no mood to be cooperative.

After the shock of the shooting, Adriana discovers, horrified, that Angèle and Jeff are her new associates. Pressed to get rid of it, she turns to her former mentor, André Vatine. The Rubens must urgently reimburse poker players. They then call on their hacker friend, Lukas, to find out who is behind the robbery.

Young ambitious chef, Adriana dreams of stars and is about to open her first restaurant. But his partner's troubled dating could well ruin everything. Forced to host an illegal poker game hosted by siblings Jeff and Angèle Rubens in her back room, Adriana struggles to stay in control on opening night.
