Shen Xiao, a genius in cardiac surgery, spent ten years in the operating room admitting that he was his lifesaver. When the benefactor he thought was the hypocritical vice president of the hospital, the nurse Zhou Zhao who really saved his life silently stitched up every life and death crisis for him in the emergency room. As media reporters make a comeback, young medical students secretly collect evidence, and security directors guard silently, a medical shady story that has been buried for ten years is being torn apart - who is the person he wants to save? Shen Xiao almost made a mistake during a high-risk heart bypass surgery and was saved by nurse Zhou Zhao on the spot. He once again mistook her for his lifesaver, but he didn't know that she was the woman who blocked the car door with her body and was seriously injured but then disappeared. At the same time, media reporter Jiang Sui returned with key videos, revealing that there was another hidden reason for the accident that year; Zhou Zhao's niece Lin Xiaoxiao mistakenly believed that Shen Xiao was the culprit of her father's murder, and began to secretly collect evidence; security guard Huo Yan secretly reported the incident in order to repay the favor; vice president Chen Yan was working step by step, trying to cover up old crimes with a new surgery case. Shen Xiao gradually discovered that his memory was confused, and Zhou Zhao was struggling between protecting and escaping - she didn't dare to recognize each other, for fear that he would hate her for hiding it, and she was even more afraid that she would become his new shackles of guilt. When Lin Xiaoxiao found Zhou Zhao's husband's autopsy report, which revealed that the accident was directly related to Chen Yan's drug tampering, Shen Xiao personally exposed the vice president on the stage of life and death. Zhou Zhao finally showed up, but Huo Yan died trying to cover her. Shen Xiao held her trembling hand and asked: 'That night... Why did you run away? ' Zhou Zhao replied softly: 'Because you're alive, that's enough. ' The operating light went out, but a new truth just emerged—Jiang Sui's sister, who was a witness to the car accident back then, is still alive in the underground clinic.
