A year and a half ago, Lieutenant Colonel Yan Ozerskiy was accused of killing a certain Lyudmila and arrested. But thanks to the competent work of the lawyer, the position of Yan himself and some minor inconsistencies in the circumstances of the case, the court acquitted him. Ozerskiy wants to return to the service not only in order to take revenge on Effendiev, who, as Yan is sure, organized his "landing", but also because he does not know how to do anything else but search for criminals.
