A group of kids whose adventures take place in the real world but also in a parallel and virtual world, Xanadu. The story? A boy of about twelve, Odd, arrives one day in his new neighborhood and quickly understands that his friends are gifted with extraordinary powers. Yumi, for example, is telekinetic while Ulrich has the gift of displacing himself at the speed of light. These kids have in fact penetrated the secret of Xanadu, the fruit of the labours of a research group whose laboratory, set in an environment inspired by the old Renault automobile factory on the ÃÂle Seguin at Boulogne-Billancourt, is now abandoned. Created by the Professor, a learned eccentric who sunk into madness, Xanadu and its multiple disturbances threaten to destroy the real world
