Vladimir Filimonov

The KGB of the USSR is alarmed by the CIA's attempts to penetrate the secrets of the laboratory of Nobel laureate Nikolai Basov, which develops lasers for missile defense. KGB Colonel Valentin Simagin recruits Kim Nikanorov, a former laboratory employee turned currency speculator. It should become a channel of disinformation for Americans about the laboratory's activities.

Based on the short story of the same name by N. Lavrov. The story is inspired by real events that took place in early 20th-century Saint Petersburg.
