Plot

Operation "Resident", which lasted 15 years, is coming to an end. But the indestructible agent of "Nadezhda" has one important mission left. Agent Carl Brockmann, who intends to steal the work of Academician Nikolai Nesterov in the defense sector, has been abandoned in the USSR. KGB leadership asks Mikhail Tulyev to return to the Soviet Union to find the spy. Meanwhile, Brockmann recruits former fascist collaborator Mikhail Kutepov for involvement in a dangerous operation.
