Lou Bertignac is 13.
She has an IQ of 160 and a deep fear of standing in front of the class.
At home her father puts a brave face on things but cries in secret in the bathroom, while her mother rarely speaks and hardly ever leaves the house.
Lou seeks escape from this silent misery at the Gare d'Austerlitz, where she finds grand emotions in the smiles and tears of arrival and departure.
One day her life is changed irrevocably when she encounters No, a girl who lives on the streets of Paris.
