Li Xiangnan is reborn in 1978. When his wife, Lin Chuqiao, asks to return to the city and break off their engagement, he abandons his former submissive attitude and decisively agrees. He then achieves outstanding results in an examination and secures a position in the emergency department of a private hospital. Despite the poor living conditions and the difficulties caused by jealous colleagues, Li Xiangnan relies on his exceptional medical skills, far ahead of his time, and his calm temperament to overcome one emergency after another, successfully treat critically ill patients, and drive reforms within the hospital department. He quickly earns the admiration of hospital leaders, colleagues, and ordinary people.
