Nicolas, a typical boy, has a father, a mother, and neighbors just like any other. But what makes him special is his circle of friends and the adventures he experiences with them. Among his companions are Clotaire, known for his dreaminess; Agnan, the exemplary student; Maixent, the magical spirit; Rufus; and Eudes. Marie-Edwige is also there, famous for her talent for organizing competitions like cartwheeling and pie-eating.
