Inspired by true events that occurred in France in the mid-'90s, this French-language feature explores the relationship between two best friends who come from opposite sides of the tracks. Delphine (Maud Forget) is 14 years old and shy, a delicate and studious high-school patron who comes from an upper-class background. After following around Olivia (Lou Doillon), the new student at her high school and a dreadlocked, outspoken outcast, the two develop a close bond. Olivia is from a broken home and has a free-spirited approach to life. One night, Olivia takes Delphine to a nightclub where they meet Laurent (Robinson Stevenin), a brooding teenager with whom Delphine falls instantly in love. Olivia similarly falls for Laurent's friend Alain (Maxime Mansion) and the four enter a free-wheeling world of parties, alcohol, and sexual experimentation. Delphine becomes immersed in the prospect of belonging to someone and begins to sacrifice some of her cherished beliefs to satisfy Laurent. Olivia, the more world-weary of the two, spots Delphine's blind dedication and tries to help her achieve happiness without succumbing to the indulgent depths to which the foursome is rapidly becoming accustomed.
