The story takes place in a post-apocalyptic future after a major nuclear war that destroyed much of the northern hemisphere. Remnants of humanity survive in South America, Africa and Australia, as well as a few in space. The consequences of the conflict on the planet are described: radioactive contamination, mutations, new religions and cultures. The narrative focuses on Latin America, life in new cities, its technological advances and the mythology that emerged around the areas still irradiated from the north.
