Mathilde, aged 9, enjoys her last day of summer holidays at the seaside with her group of friends. Her father falsely interprets one of their games.

Céline is expecting her firstborn. But she’s not the one who’s pregnant. In three months, her wife Nadia will give birth to their daughter. Under the gaze of her friends, her mother, and the law, Céline looks for her place and sense of legitimacy.

In the maternity ward, Céline awaits the arrival of her first child. It is Jeanne, her partner, who will bring her into the world. At night, in the entrance hall of the hospital, she meets men who are waiting, like herself.
