Cooperative supervisor Ma Degui has an overbearing work style and refuses to accept life-saving grain facing heavy rain simply because his "hat is not worn straight." Cooperative president Li Jianguo is no longer willing to endure it, and his cousin Zhao Dashan steps forward. Facing deliberate difficulties, Zhao Dashan relies on solid experience to protect the grain in the rainstorm, and withstands the pressure to take on the heavy responsibility of grain collection. They not only repelled Ma Degui in the contest, but also uncovered cooperative corruption, establishing a new, open, and transparent grain collection process. The story demonstrates the positive energy of breaking old rules, upholding fairness and justice, and safeguarding farmers' interests through hard work.
