Herder Pagwa lives in a hut in a valley of beautiful flowers, where he hoards a mysterious chest whose secret is not revealed even to his three sons. The elder two believe that the chest is filled with gold and precious stones, so they break it open. From then on, water floods the valley, the earth withers and the people and animals start dying of thirst. The youngest son seeks out the wise Arat to ask for advice.

It is reflected in the lives of some narrow-minded people who discriminate between work as black and white, evaluate acquired skills and acquired experience only by a certificate, and confuse friendship with love. Bayasgalang's childhood was spent on the back of a racehorse, and his teammate studied at school in Darsuren and returned to his hometown as a teacher. While Darsuren and his students were walking in the countryside, an artist from the city attacked and painted them. Misunderstanding the mutual respect between the artist and the teacher, Bayasgalan went to the city to accept the idea that horsemanship is not a profession, and he faced great difficulties in not finding a job. On the way, he meets an artist who is suspicious of Darsuren, his wife and children, and introduces Bayasgalan. He tells the story of how he is returning to his hometown after realizing that he has wasted his time by abandoning his profession to be suspicious of an innocent man.
