In the Apsheronsk District of the Krasnodar Territory, among the majestic Caucasus Mountains and impassable forests, the tiny villages are lost. They are connected to the rest of the world only by a thin thread of a narrow-gauge railway winding through gorges – and this is the only way there and back. A small old trolley car-raiser nicknamed “Matrix” by the locals delivers food, fuel and other benefits of civilization every day. People who for whatever reason prefer loneliness and unity with nature to noisy city life make their journey by “Matrix”.
