Set during a sultry summer in a French suburb, Marie is desperate to join the local pool's synchronized swimming team, but is her interest solely for the sake of sport or for a chance to get close to Floriane, the bad girl of the team? Sciamma, and the two leads, capture the uncertainty of teenage sexuality with a sympathetic eye in this delicate drama of the angst of coming-of-age.

The story revolves around 22-year-old Laure, who is trying to find her feet. After performing brilliantly in her literature studies, she enrols as a communications officer in the Naval Fusiliers. She will quickly have to adapt to and assimilate the rules that apply within the institution. But Laure is a determined woman, and she has a thirst for knowledge – still. A thirst to learn to get to know and be comfortable with herself, and to find her place.
