Four friends from a provincial mining town receive an order from "above" to intimidate and drive away a visiting blogger from the capital, who intends to highlight local environmental issues and raise the issue of a brown coal fire in a local open-pit mine. But from the very beginning, everything goes wrong for them: lateness, alcohol, arguments and inexperience make their own adjustments, and they themselves find themselves under fire.

This is the story of gray-haired Nikolai Borisovich, a teacher and mentor, who one day gives up his career and gets a job as an ordinary courier in a multi-profile company. From the very beginning of the film, we see a determined old man who fulfills orders and step by step climbs the career ladder. Nikolai Borisovich always has an old Polaroid camera around his neck, and he records each new success and sends the photo somewhere in an envelope... Overcoming obstacles, Nikolai Borisovich, a true teacher by vocation, will prove that in one summer you can build a happy life. The main thing is to do it honestly. Just live.
