Rejecting the original plot, she resolves to end her engagement to military officer Lu Hanchuan and build an independent life in Beicheng by finding work with her medical skills and taking the adult college entrance examination. She first demonstrates her abilities by outsmarting human traffickers aboard a train. Facing prejudice from the Lu family and Bai Yingying's schemes, she relies on her medical expertise and integrity to overcome crises, save Grandma Lu, and heal Lu Hanchuan's old injury. Ultimately, she establishes herself at the Wen family clinic and earns admission to university. From clashing with Lu Hanchuan to falling in love with each other, they forge a life of triumph and transformation in the 1980s.
