In the early 1980s, the struggle for power intensified among the party elite of the USSR. Leonid Brezhnev's illness and total corruption have forced the security forces to choose what the future of the country will be. Ordinary people find themselves drawn into a merciless conflict between two departments, the KGB and the Ministry of Internal Affairs, for power. One evening, a troubled teenager comes to the local police officer, senior police lieutenant Kirill Nesterov, with a suspicious package containing rare canvases by Russian artists. Kirill had no idea that this episode would become only the first step in a series of further events that would threaten not only his views on life, but also life itself!

The year is 1943. Anna Petrova (Katerina Shpitsa) is a combat pilot who was seriously injured. She returned to the rear and works as a leading engineer at an aviation plant, where new Gyrfalcons aircraft are being prepared for testing. The plant's management, unaware of the consequences of her injury, instructs Anna, together with Major Zotov (Alexander Gorbatov), to drive the prototype of the "Gyrfalcon" to the front. In addition to the desire to defeat the enemy and return home with a victory, Anna pursues a personal goal. She is determined to get even with Major Briggel, the German pilot who killed her lover.
