Employees of the Gloria Agency, at the request of lawyer Yuri Gordeev, with whom they often cooperate, are investigating the circumstances of the suicide of an officer of the Federal Security Service. However, it soon becomes clear that this case is beyond the scope of a private investigation, and Alexander Borisovich Turetsky takes it into his own hands. And the strange thing is, for some reason, it is constantly put spokes into the wheels by precisely those services that should be most interested in establishing the truth. It turns out that the prehistory of this crime is a thing of the past, when the "all-seeing eye" of the notorious 5th Directorate of the KGB was actively watching dissident citizens.
