Noël and Guy, two young Grolanders from Frincheux, tired of their condition as eternal unemployed temporary workers, decide to become the Steve Jobs and Larry Page of the Presipauté grolandaise. How? By marketing their invention which they consider revolutionary: an injection foam intended to stuff animals. Noël and Guy then go to the capital to patent their project and find investors. Will their stupid invention make followers? In any case it will do damage, in Groland as in Paris.
