Every year, the residents of Carillon road await the tradition of decorating their houses for the holiday season with great anticipation. And for good reason -- everyone wants to win the "Holiday Splendour" contest and receive the prestigious golden cane. But this year, to everyone's consternation, the new Kosky family refuse to decorate their house. At first, the others try to get them to join in using peaceful means; however, the methods of persuasion gradually become more and more intimidating. Then the unexpected happens: the unforeseeable incident that will change the course of the future and cast a special light on these events of everyday life. La guerre des lumißeres illustrates how conflicts are born and makes us think about human and social relationships. A simple story seen through the eyes of a child, it is an excellent lesson in humanism.
