Lu Wenting, a middle-aged ophthalmologist, suffered a sudden myocardial infarction due to overwork. At the same time, Lu Wenting's classmate and friend Jiang Yafen left China. After graduating from college in the 1960s, Lu Wenting, who was in her forties, was assigned to a hospital as a resident, and later married Fu Jiajie, who was engaged in metallurgical research, and had a son and a daughter. Busy housework, narrow living space and intense working and living rhythm have brought great pressure to Lu Wenting. However, no matter how tired, nervous and difficult, Lu Wenting forgot everything as long as he faced the patient's eyes. One morning, she had three operations for Vice Minister Jiao, Zhang Laohan and finally fell ill due to fatigue. In the process of coma and sobriety, hazy memories of various fantasies flashed from the depths of our consciousness: lonely childhood, monotonous and busy college life, sweet love, husband and children, friends Jiang Yafen's dinner abroad, and Qin Bo, Vice Minister Jiao's wife, looked embarrassed and distrustful. She thought she would never get up again. Then, after a month of treatment, she finally escaped death and walked out of the hospital with the help of her husband in the morning sunshine and cold wind.
