The hero of the film, academician Sergei Vasilyevich Lunin, director of the Kiev Research Institute of Informatics, is working on the implementation of the Unity project in the enterprises of a single department. According to his calculations, this global information network should significantly reduce the number of intermediate instances and, accordingly, the decision-making time. Lunin has opponents. Despite a sharp deterioration in health, the hero goes to the Novogorsk Tractor Plant and there he finds out the real reason for the downtime, and, consequently, the reason for hiding the data. Knowing that he has only six months to live, Lunin abandons the operation and does everything possible to protect his project.
