Due to her inability to bear children, Lin Qiuyan was ruthlessly driven out of her home by her ex-husband's family. Left with no other way out, out of spite she married Zhao Dahan, the "foolish husband" mocked by everyone in the village. After marriage, refusing to submit to her fate, she started an ecological aquaculture business on her own, yet repeatedly faced harassment and suppression from her ex-husband and the village bully. In every crisis, the seemingly foolish Zhao Dahan silently guarded her side, helping her resolve issues in unexpected ways. Until one accident when Zhao Dahan recovered his memory—he turned out to be an agricultural research institute expert who had been missing for many years. The couple joined forces strongly, staying in the village to jointly build a modern agricultural industrial park and leading the villagers to common prosperity.
