A biography of Jorge Luis Borges working from an exhaustive review of the papers he left, the books he read, the places he went to. And with this, an attempt to decipher a very peculiar life: someone who lived like a hidden, underground warrior, whose cause was literature, literature conceived as a kingdom and as a landscape. If Cold War spies fought from their desks or from an uninhabited house to defend their half of the world, Borges strove from a library to elevate and broaden the territories of his own tribe: the people for whom the most important part of the universe is books, plots and words. This film is devoted to that secret pilgrim (to borrow from Le Carré, the king of all spies).
