After returning from studying abroad, Zhang Yaning brings back sensors capable of issuing an avian flu warning 72 hours in advance, but her father-in-law, Chen Liqiang, firmly opposes her plan. With the support of her husband, Chen Mo, Zhang Yaning first tests the sensors at her family's chicken farm. The sensors successfully predict an outbreak, while other farmers who did not install them suffer devastating losses. Chen Liqiang finally comes around and hands over his position as chairman of the county's Chicken Farming Association to Zhang Yaning. She then builds a smart poultry farming data hub, but her brother-in-law, Wensen, conspires with Mr. Zhao of the Lüfeng Group to sabotage her. Turning their scheme against them, Zhang Yaning sets a trap that exposes and captures both men. In the end, she leads poultry farmers across the county in upgrading their industry, and the data hub becomes a model project at the provincial level.
