A biography of Jorge Luis Borges working from an exhaustive review of the papers he left, the books he read, the places where he went. An attempt to decipher a very peculiar life: someone who lived like a hidden, underground warrior, whose cause was literature, conceived as a kingdom and as a landscape. Borges strove from a library to elevate and broaden the territories of his 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).
