Jeanne is traveling to Romania to celebrate her bachelorette party with her friends when she meets Nino and his family. They are worlds away from one another, yet for the two of them it is the beginning of a passionate and timeless summer.

In a bourgeois, intellectual, and elitist Paris, three sisters who couldn't be more different are going through a period of doubt and self-reflection. The eldest is caught up in a torrid affair with a female painter. The middle one is bored with her introverted computer scientist partner. The youngest is emerging from the grief of losing her fiancé. It's autumn, Christmas is approaching, and each of them longs to change everything in her life.
