In the Apsheronsky district of the Krasnodar Territory, among the majestic Caucasus Mountains and impenetrable forests, small villages were lost. They are connected to the rest of the world only by a thin thread of narrow-gauge railway winding through the gorges, and this is the only way back and forth. A small old trolley railcar, nicknamed by the locals "Matrix", every day delivers food, fuel and other benefits of civilization. People who, for one reason or another, prefer loneliness and unity with nature to noisy city life make their journey on it.
