Years after the death of his father—who in the 70s sacrificed everything to join the guerilla army in Mexico—the narrator tracks down his younger brother, hoping to piece together the fragments of their family history. From the start, the elder brother's memories were more intense than his brother's, which were vague. But memory is potent when collectively called upon, and the brothers share a wrenching journey while reconstructing their past and their memory of the father who lost his life in the pursuit of his ideals.
