Su Xiaohe, a 22nd-century agricultural science PhD, travels back in time to 1977. At the outset, she is framed by her stepsister and ends up trapped in a dilapidated house with He Yuan, the poor, rugged bachelor whom the entire village avoids. Refusing to give in to fate, she uses scientific farming methods to improve saline-alkali soil, detoxify potato seeds through physical methods, and make her own pesticides to fight insect infestations. Not only does she lift the He family out of poverty, but she also leads the entire village to prosperity. Facing troublesome relatives and oppression from the production brigade leader, she joins forces with He Yuan to establish a canning factory, build a transport fleet, and contract barren hillsides, turning worthless land into a mountain of gold.
