Imagine if rainbows were actually time travellers? 10-year-old Arco lives in the distant future. During his first flight in his rainbow suit, he goes off course, loses control, and lands in our near future. Iris, a little girl who’s the same age as Arco, sees him fall from the sky. She will do everything she possibly can to help him go back home.

Il ne reste plus aucun homme sur la planète Terre, seulement les robots d’entretien qu’ils avaient programmés. À la tombée de la nuit, Mikki, le robot de l’Opéra Garnier, projette tous les soirs sur la scène les images mystérieuses d’une danseuse.
