In the sleepy town of Turner Falls, where many wealthy families live, something strange has been happening lately. At school, due to an incomprehensible outburst of aggression, a student kills a teacher right in class. Then people begin to disappear, problems with communication appear, and perhaps the cause of the events needs to be sought in a biological laboratory located not far from the city. But there will be no investigation, because soon local teenagers will suddenly turn into blood-obsessed sadists, instead of television shows and telephone beeps, a signal will be heard, driving everyone who hears it into catatonia, and the miraculously surviving group of people will have to survive, trying to find out what happened. And no, it's not the virus. And zombies have nothing to do with it either. Everything is much, much worse.
