It is believed that only real heroes are able to protect life on Earth. But to do this, they must know about the impending threat. What happens when the heroes don’t even feel that danger is somewhere nearby? When they do not suspect that the army of the night is ready to fall on this world? Then the night inhabitants of the Earth, no different from people, come to protect all living things. So it is, because they are infernos - ordinary guys and girls, just like their peers. Only they, infected with a special parasite, know about their difference from “normal” people, because of which the common people call them an offensive word... “vampires.”
