Researcher of one of the research institutes Pavel Sokolov, who recently lost his job, has the opportunity to earn good money - on the instructions of a friend-businessman, he goes to the rural hinterland, where he must persuade Maria Loshkarova to sell her dairy farm for a business project of city businessmen.

Paul, without even noticing, falls in love with Mary. Now he has to make the difficult choice: not to execute a friend's assignment or go against conscience.
