Lou, a creative and dreamy 12-year-old girl, lives alone with her mother in an orange building with tons of little balconies that give access to the roof. Mina has been her best friend since kindergarten, and Lou has been in love with Tristan, one of her neighbors, since elementary school. Her mother has relinquished her own personal happiness of late so as to devote herself to her daughter, but their little bubble bursts when Mom meets a man and Lou at last dares speak to Tristan.

Do we really know our parents? Fourteen-year-old Anouk suddenly discovers another side to her mother during an observation workshop that she carries out in the insurance company where her mother works. An immersion week in the company's adult world, with its little compromises and many cowardly acts, which soon put a seal on her young life. Between an initiation, rift, and assuming responsibility for the first time, the experience is a form of adieu to childhood.
