In the middle of the 21st century, all humanity rejoiced. The threats of war, climate disasters and famine are a thing of the past. Far beyond the orbit of the Earth, a group of sentinel satellites protected the internal system from any uninvited guests. The discovery of the genetic code of the last of the unknown viruses seemed to forever protect civilization from the epidemics that threatened it. Man, in his development, has reached all heights, anticipating the next evolutionary leap - a leap to the stars. But in the depths of the technosphere he created, a danger was already brewing, ready to develop into a global pandemic. A pandemic of unknown nature that will throw humanity back to the Stone Age.
