Sébastien, 7 years old, worships his mother (Emmanuelle Béart) – in his dreams, she is a queen. He pays little attention to his father (Jacques Gamblin), a failed inventor who’s never around.
When a new neighbour, Philippe (Stefano Accorsi), moves in next door, Sébastien is sure to have discovered his mother’s prince charming. He now has a mission: unite his mother with her prince.
As the boy gets closer to Philippe, so does his mother. His dream may not be out of reach, but it will have consequences.
