It's a difficult task to fight werewolves, vampires and undead. Not everyone can master it. For this, not only desire is necessary, but also a certain heredity. Sanka Konovalov heard a lot about his ancestors, but never about the fact that they were hereditary witchers. And he learned about this only on the day when danger awakened his witcher habits. From that time on, he was taken into service in the top-secret Department, where he began identifying and exterminating the undead. And every time he came across things more and more complicated and confusing, until one day a harsh denouement came.
