The room in the name is a work office where four employees sit. Three old-timers: Albina, Lyudmila and the eldest of them all, Elena Alekseevna. The fourth is Lisa, a very young, extremely principled girl who recently graduated from college. This team, one might say, is a kind of ecosystem where everyone has their own role. Therefore, despite the friendliness, there is a lot of guile in their relationship. So, Albina came up with a certain Konstantin from the Baltic states, with whom she had an affair. One fine day, she decides to develop this story and advertises a room for rent in order to find a person who will agree to play the role of Konstantin, who came to visit her.
