The great changes in social life and people's minds in Mongolia before and after the revolution are lived in the form of Dolingor, the humble servant of rich Bold, hard worker, and Bat, who fought against slavery and gained freedom. Dolingor only talks about the joys and sorrows of meeting Myada and the happiness of his soon-to-be-born child only in the dark days of the night. Rich Bold argues with his wife about adopting a son to watch over the hearth. Rich Bold, who was told by Monk Lovon that he would not be happy to leave Dolingor, is moved to leave Myadag, who is about to give birth, on his black manure. When Dolingor rushed to evict Boldyn's house, a "lost girl" was born. Dolingor, for the sake of the rich Bold, cheated the Naudiragator with a stone bribe, and was forced to serve in the military for many years. Going like this, when he enters the house of the station, he meets his daughter, and the story of the movie begins.
