Vanille is a Parisian child who has just arrived in Guadalupe for her holidays. But these holidays will be different. We join Vanille as she meets Aunt Fréderique, who is possessed by a spirit, the young Oba, half-boy and half-tree, and also the mysterious Titan Arum flower. An epic and otherworldly adventure, full of magic and vivid characters, that encourages us to discover the unknown, while offering a reflection on the importance of finding our roots. All of this is given a finishing touch of the Creole language.
