The film tells about the people who built a full-flowing river in the very heart of the Black Desert — the Karakum Canal, linking the waters of the Amu Darya and the Caspian Sea. Life and work in the desert are far from easy, yet the film focuses not on the harshness of everyday life but on the moral atmosphere within the working collective.
