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.

At a moment when she is preoccupied by the imminent closure of the maternity clinic where she works, her life is further turned upside down when Béatrice, her father's former mistress, turns up on the scene. Béatrice is a capricious and selfish woman, Claire's exact opposite.
