Chen Shaochang (Shi Hui), a primary school principal widowed at a young age, raises his children alone. His close friend's daughter, Liu Minhua (Zhu Jiachen), whom he hasn't seen for many years, begins working at the primary school through his introduction. Chen Shaochang's son, Jianzhong (Han Fei), and daughter-in-law, Feng Lijun (Li Huanqing), consider Chen's job undignified. After retiring, he is filled with melancholy, understood only by Minhua. Although their relationship deepens, they must contend with the ethical and social norms of Republican-era Shanghai.
