Nous trois

Six-and-a-half-year-old Sébastien is a sensitive, highly imaginative child. Despite the affection he feels for his father, a dreamy inventor, he notices his mother's loneliness and how there is a lack of love in her life. When they move the house, it won't be long before he sees in Philippe, his new neighbour, an ideal Prince Charming for his mother. (imdb)
