The Moscow metro is not only an underground architectural monument, but also high-speed transport. It takes just over an hour to get from one end of the city to the other. It will take a long time to try to travel like this in a personal vehicle, “collecting” all the traffic jams and traffic lights. Andrei Mikhailovich, a simple law enforcement officer, also enjoys using this transport. But one day, for him, the subway became not just transport, but a whole testing ground, one of which he is ready to tell from his memories.
