Dondog, a young man who grew up on a horse mane, becomes a cowherd after being reprimanded by the management for killing his horse in a race with a car. On this occasion, the relationship between Yanjmaa, a driver who came to the collective, Gonchig, who comes to trade for personal gain, and Dondog, a horseman, was shown in light comedy.

The story begins when the forensic doctor Torbat's mother, who is in love with him, estranged her from her daughter for "doing dirty work".
