With the help of a gruff old neighbor, a little girl from Limoilou, blessed with a fertile imagination, sets out to make her father happier.

Seven-year-old Anna admires her mother, who is both victim and aggressor in her tumultuous relationships. Through a forbidden tube of lipstick, the little girl tells herself the imaginary story of a trapped princess: a fantastic fairytale in her eyes, but also the distressing reflection of her mother’s reality.
