Michel Vaillant is the star of all the biggest international motor car racing circuits, and he's revving up for a whole lot more than just a spin around the block. The Vaillant team find themselves up against new sporting and technological complications, and also some disconcerting changes in the world of motor car racing. The fate of the Vaillant dynasty is in the hands of three generations of men and women. The first challenge is to fight their way to the top, starting with the WTCC, the competitive world championship for touring cars. The second is to try and keep the family together, despite the opposing views of its members.
