The stationmaster of a small railway station, Yakov Ivanovich Golovach, is obsessed with reading historical novels about knights. Fancying himself as the hero of one book – Don Diego - he loves to fight with an imaginary opponent. He is caught in the act by the female residents of the surrounding villages who came to the station to meet the arriving mail train, in order to sell foodstuffs.

The laughter of the peasant women makes Yakov Ivanovich furious. In a rage, he orders the detention of violators of the railway rules who are crossing the railway line. But he only manages to catch the dawdling old woman Pelageya Diomina ...
