If you shoot the past with a pistol, it will answer you with a cannon. Police captain Igor Doroshin was convinced of the accuracy of this statement by taking part in the investigation of the case of a maniac who killed children in the distant seventies. And when, years later, Igor and his friends took up him, it "fired" a new series of murders, blackmail, and deception. They are alive - persons involved in that long history: businessman Argunov, and a major official Sitnikov, and former policeman Zabelin, and writer Istomina. After all, it only seems that the past is far away. The spiral of life shrinks tightly to inexorably straighten out and reward everyone according to their merits.
