Naima (Lise Lomi) is a naive and simple 16-year-old girl. Summer vacation is coming, and with it comes Naima's long-awaited birthday. After this birthday, Naima will take another step towards the seemingly colorful adult world. In this summer, her cousin Sofia (Zahia Dehar), who has been living in Paris, returns to Naima. Sofia is different from all the girls Naima has ever seen, and she exudes a mysterious charm. Naima was soon deeply attracted to Sofia. Sofia's existence made Naima and her good friend Dudu (Clotil de Courau) drift apart, and even betrayed the previous agreement between the two. At the beach, Sofia met a man named Anders (Benoît Magimel), who exuded an artistic atmosphere that fascinated Sofia.
