Humanity is again on the verge of extinction. There is a brutal bloody war in which there is no place for mercy and compassion. Only a small group of people survive. They are looking for their hard way in this cruel world. They fight for their lives literally every minute, with it day and night. They are becoming smaller with each new fight with the enemy. They're trying to rebuild the human race. But this idea is so unprincipled and terrible that it amazes even seasoned human species. The time has come when there is no room for common sense. It is necessary to obey only instincts, in particular self-preservation and procreation.
