A world in which life is possible only under the dome of cities. A world in which infertility has overtaken humanity, and the remaining families that do have children are forced to give them up for adoption. A world where social rating is everything! Someday it had to collapse. By coincidence, the children of the main characters are left at home alone at night. And it is at this moment that the apocalypse occurs. Hordes of bloodthirsty creatures from contaminated lands, previously considered lifeless, poured into the city through which the heroes must pass to get to their children. Will they have time to save them? Will they find a safe place? Will the family be able to get out as a whole? What awaits people after the end of the world?
