The worst scenario of the near future has been realized: a deadly virus has broken free, decimating cities and countries. Populated areas are deserted, people survive as best they can, gangs of marauders are rampant everywhere... As a result of risky medical experiments, not only a virus was born, but also a telepathic dog named Grozny. A dog cannot do without a person. But those people to whom the dog attaches himself will soon no longer be able to do without him. Grozny is able to pull his friends-masters out of the most disastrous scrapes, he is able to sense what is inaccessible to humans.
