The male protagonist Gao Yuan and Qu Zhengping are good friends with a very strong relationship. More than 30 years ago, in order to exchange food for the hungry villagers in the village, Gao Cheng'an, the village head, killed the big green horse that grew up with his son Gao Yuan in exchange for food. In order to avenge his father, Gao Yuan, who is not sensible, exposed his father's false report of grain production at the county's grain commendation meeting, and his father was severely punished for this. After experiencing a series of incidents caused by food, with the help of Accountant Liu, Gao Yuan successfully finished his studies and walked out of this poor and backward place

More than 30 years later, Gao Yuan returned to his hometown as the new director of the Department of Grain. However, not long after he took office, he received a report letter claiming that the current grain depot was just an empty warehouse, and he directly pointed the finger at Qu Zhengping, who had become the deputy governor. In order to find out the truth of the incident, Gao Yuan decided to launch an investigation, but was obstructed by forces from all directions.
