Tanya is dating a very businesslike and very married Andrey. At the same time, she accepts the advances of Renat, who is in love with her, in order to annoy Andrei and cause his jealousy. To divorce him from his wife and marry herself, Tanya resorts to a common method: throwing away birth control pills. She easily manages to carry out the first part of the plan, to become pregnant with Andrei’s child, but difficulties arise when it comes to starting a family with him. Although he is imbued with passion for her, he is satisfied with the existing state of affairs. Things must move - either forward or backward. And then another participant enters the game, whose appearance came as a complete surprise to everyone. It was he who broke the existing love polygon and tailored his figure. The events unfold against the backdrop of everyday life at work. Andrey is a co-owner of a dealer company for a large industrial enterprise; in addition, he owns a company selling medical equipment. He is “covered” by a former security official who uses his administrative resources to resolve issues in various government agencies. In particular, he ensures the elimination of competitors in tenders in which Andrei's company participates. Ill-conceived financial policies and investments in unprofitable projects threaten Andrei with bankruptcy, and in order to save the situation, he takes out a loan and borrows money from friends at a high interest rate. He is faced with the task of choosing one single core area of activity, cutting off unprofitable businesses in order to save those that bring real income. But this is not easy enough, because everything is tied into one knot. The situation is complicated by the fact that Andrei’s relationship with the security officer covering him suddenly turns out to be irreparably damaged. The narrative is based on real facts.
