Belarusian border guards detain cargo being illegally transported across the Dnieper section. However, the contraband turns out to be one of the anti‑aircraft missile systems stolen in Ukraine. To investigate this case, OSAM — a separate service for active operations — is involved. In addition, the Ukrainian side sends its own agent to participate in the investigation. The MANPADS must not be let loose, but there is no trust between the parties.
The action of the new film unfolds against the backdrop of the collapse of the USSR. Border guard officer Anton Pekarsky, having gone through the war in Afghanistan and served ten years on the border in Central Asia, becomes unnecessary to the state that is falling apart and returns to his native Belarus. However, the knowledge and loyalty to duty of the experienced border guard turn out to be in demand in his homeland, where new national border protection services are being established.
