Yura Voskoboinikov and Sergei Altyntsev are friends from school. Together they went to college and graduated with honors. Further distribution pelts friends in different parts of the country. Sergei is left at the factory in the capital, and Jura goes to the far Ural plant. For a while, they kept in touch, and Sergei even took one of the Yuri’s ideas for his purposes. After many years, they will have to stand up for each project. Only one of them will be put into production, and the old resentment has been contaminated with this instant rivalry.
