A parody of anthropology, linguistics, and cultural imperialism. The film follows an unlikely team of linguists into the wilds of an ersatz Patagonia to study the last speakers of a dying language. That language apparently consists of a single word, which therefore means everything.

Au bord de la mer du Nord, un anthropologue et sa femme font la connaissance d'un certain Narciso Campos, qui les invite dans sa maison de Patagonie où se trouvent les deux derniers Indiens Yagan existant au monde.
