Family man François Nouel (Clovis Cornillac) is the number one fan of the Tour de France – an obsession that costs him his wife and his job. At a loose end, François meets a former sports manager, Rémi (Bouli Lanners) who encourages him to take the plunge and do the Tour himself. With nothing to lose, François sets off, always one day ahead of the race, attracting fellow amateurs, media coverage and cheering crowds. As obstacle after obstacle is thrown his way, and his family comes back on the scene, François discovers what is really most important in his life.
