A lethal drug used for recreational purposes (Karmadol) grants access to the memory of our last life before reincarnation. This alters everyone’s perception about themselves, since it puts on their backs the weight of merits and demerits of the previous life. Thus the past acquires such weight that somehow the limits of present time are blurred, and society becomes obsessed with the past. This is the context in which the characters live: Carlos is a mediocre science-fiction writer and manager of an 1860 Alexandrine hotel, Mirta is a goat veterinarian in Spain of 1550, and Lazlo is a marketing manager and Languedoc Crusader of 1200. A simple menage-a-trois turns into a crossing of historical periods, languages (Egyptian, Archaic Spanish, Provençal and modern River Plate variety), together with an unceasing pain that persists even after 500 years.
