Sanya and Natashka, small farmers from the Kuban, show up at an elite mansion on Rublyovka, where Natasha's sister Ninel, the wife of a very big businessman, lives. The sisters had not seen each other for exactly twenty years - they quarreled to the death after the day before the wedding, Natasha took away her fiancé Sanya, her current husband, from Ninel. And now Natashka and Sanya come to Ninel to help them find their son who has gone on a spree in Moscow. It all starts with a scandal and old grievances, there is a quarrel after a quarrel, but in the course of the action, the sisters are getting closer and closer, forgiving each other. As a result, the missing son is found, and even with the bride, and it is not Sanya and Natasha who receive help, but Ninel herself, whom her sister and her husband with the Kuban pressure help to establish a failed business and return the lost spouse.
