Shi Lin is a master of surgery, calm as ice, but after a failed operation, he was surrounded by the entire network. Only Wen Zhao - she was his intern and now a top medical investigator - personally handed over the evidence to expose the medical malpractice he had concealed. She didn't cry or make trouble, she just said: "You taught me sterile operation, but you didn't teach me how to save people's lives." He lost everything, but she set up a dragnet in the dark, forcing him to face the truth that was covered up back then. When the cold night fell, she handed him a fatal antidote, not to save him, but to keep him alive to repent.
