Born and raised in the city, Sang-woo quickly comes into conflict with his old-fashioned grandmother and his new rural surroundings. Disrespectful and selfish, Sang-woo lashes out in anger, perceiving that he has been abandoned.

When Sang-woo s mother finds work and finally returns for him, Sang-woo has become a different boy. Through his grandmother s boundless patience and devotion, he learns to embrace empathy, humility and the importance of family.
