A rockfall from space forever changes not only the earth's surface, but also the fate of people, although most of them do not even realize that the world is hanging by a thin thread. The terrible threat posed by an alien with a heart of stone can only be resisted by heroes with ordinary, living hearts, but they have yet to learn that the most difficult thing in a mortal battle with an alien is simply remaining human. And some of them still have the audacity to count on happiness. But sometimes death is worth living, and love is worth waiting for.
