During a raid in one of the drug houses, operatives found four corpses. All the victims died in terrible torment due to the fact that they took a dose of an unknown poison along with drugs. While the detectives are puzzling over who supplies this poison - Tajik drug addicts, Azerbaijani traders or Russian brothers - the "spoiled" drug is rapidly spreading around the city, finding more and more victims. The search for the leader of a deadly network eventually becomes like a real war. But the employees of the drug control department are not a timid ten guys, they perfectly understand that only they can interrupt this "eternal thrill."
