Lin Jianguo, the young and powerful deputy director of the Provincial Department of Health, and his wife Su Qing, the director of the cardiology department of the city hospital, are a model couple in the eyes of their medical school classmates. They and the director Ma Mingyuan have been classmates for many years, but they don't know that Ma Mingyuan has an unresolved old love for Su Qing deep in his heart.
Li Yumeng, a newly recruited graduate student, took a rash bet as a target to avenge the injustice suffered by his father during a medical accident. He used his carefully calculated admiration and youthful enthusiasm to tear open the cracks in Lin Jianguo's perfect life within a month. Lin Jianguo fell into the whirlpool of desire, abandoned his wife and daughter, and married his son. The new wife's extravagant spending dragged him into a quagmire of bribery.
At the same time, Ma Mingyuan, who had been watching over Su Qing, finally revealed his feelings that had been hidden for many years after his friend's family broke up. The hurt Su Qing turned around in the ruins and accepted this belated protection.
Lin Jianguo, whose reputation was ruined, finally jumped from the Health Department building during the "Double Regulations" period and paid for all his sins with his life. On the wall of the building, the oath to "serve the people" still shines, reflecting how ideals are lost, how deep feelings are misplaced, and how everyone has to move on except for a broken family.
Purpose: Life is a journey of constantly facing "crossroads", and every choice redefines who we are; and the true soundness of the system begins with everyone in it starting from the reverence and persistence of the inner moral law.
