In the mid-1980s, Han Donglai, a demobilized agricultural machinery operator, diligently studies agricultural machinery technology and falls in love with Lin Qiuyue, a teacher at a community-run school. Han Donglai's family members are narrow-minded, look down on the couple, and do everything they can to obstruct their marriage. Undeterred, Han Donglai seizes the opportunities of the times and starts a business using his machinery skills. Lin Qiuyue stands firmly by his side, and the couple work together to build an increasingly prosperous life. The relatives who once mocked them cling to their outdated beliefs and miss their chances to get rich. Left struggling to make ends meet, they watch the couple achieve success in both business and love, filled with regret.
