Odette has planned everything so that her daughter Mathilde's wedding will be the best it can be: the choice of caterer, the place, the seating plan, the lifelong friends, nothing has been left to chance so that this evening will be unforgettable. On his side, the caterer has also planned everything so that his first outing will be memorable. Don't worry, he won't be disappointed. He entrusted the service to two young extras, full of good will although a little novice; and the musical animation will be entrusted to an orchestra which usually plays hard-rock but which, for the occasion, will have to play only French variety. Until the moment when the extras carefully bring the cake forward, the events are calm; it is afterwards that things are going to be spoiled.
