In 1974, Yang Pojun, an educated youth, breaks his leg while repairing an irrigation canal. The brigade leader, Zhou Demao, withholds his medical expenses, and his fiancée breaks off their engagement. Just when he reaches his lowest point, he activates the Emotional Feedback System. He leads impoverished villagers in improving waterlogged lowlands and barren sandy fields, using modern agricultural knowledge to grow high-yield rice and sweet potatoes and break Zhou Demao's monopoly. After enduring false accusations, forced land clearance, and sabotage, he finally exposes corruption with the support of county officials and brings down Zhou Demao and Qiao Mancang. He establishes an agricultural extension station and leads the entire village toward food security, embarking on a new journey alongside Jiang Xiaohe.
