Zhang Yuqing, who has been working hard away from home, returns to her long-abandoned hometown feeling lost and uncertain. Faced with her father Zhang Tieshan's stubborn determination to hold on to the orchard, years of accumulated family estrangement, and the harsh reality of struggling to find buyers for their navel oranges, she chooses not to run away. She gives up her city job, puts down roots in her hometown, and uses the new knowledge she has acquired to seek new opportunities for the local oranges. As father and daughter gradually move from arguments and disagreements to mutual understanding, her mother, Li Xiulan, quietly watches over the family. Together, they overcome one challenge after another, from disasters damaging their fruit trees to buyers forcing down prices, determined to protect the orange orchard that generations of their family have cultivated. The fragrance of oranges spreads across the old rooftops, as two generations gradually reconcile through understanding and compromise.
