Latin American fiction, whether literary or cinematographic, produced in the second decade of the 21st century, has been the stage for productions about an issue that has not been collectively resolved and that still haunts various spheres of public and private life in society: the unburied past of military dictatorships in the subcontinent. In these works, it is perceived that the past as a temporal dimension imposes itself on the present and insists on not passing. The various forms of perpetration of State violence that were not dealt with collectively meant that the horror practiced in the years of exception was confined to the underground of official history. This made it possible for different narratives about historical facts about the recent past of Latin America to be contested, opening doors to movements that bury truths, to denialism and historical revisionism. Therefore, this dissertation proposes a reflection on the formal solutions that these contemporary fictions use to deal with the wounds that are still opened caused by civil-military dictatorships and the permanence of institutional violence over time. From the study of the chosen fictions, we start from the hypothesis that, in these narratives, the displacement of enunciation, the banality of evil and a ghostly aesthetic that points to the use of the body as a ruin/allegory are narrative devices that place temporality at the center of the debate.
