It’s the end of summer in the countryside. Mylia, 12, begins high school. She will have less time to devote to her younger sister Camille and to look after her parents who argue constantly. In this hostile and unknown place, she will have to find out where she belongs. Her cousin introduced her to Jacinthe, an older, more experienced girl with a network of friends. Maybe by looking like the others and joining the ranks, everything will be easier. Her route also Crosses Jimmy, a native classmate who is often in her corner.
