Hugo is 19 years old. Like every summer, he spends his holidays on an Atlantic island, in the small family house. But this year is different: Hugo has undergone a physical transformation and arrives with his girlfriend, Queen, a beautician whose lively chatter and long, glittery nails contrast sharply with the young man’s modesty and shyness. Before long, the couple becomes the focus of everyone’s attention.

Between new encounters, successes and failures, and faced with fierce competition, Sophie realizes that her dream of joining the Polytechnique represents more than an entrance examination but a true challenge of social climbing.
