Top surgeon Chen Zheng returns to the scene of a medical accident - the patient Liu Dahai is in shock due to bleeding during the operation, and the surgeon Zhao Hongyuan is preparing to use illegal hemostatic drugs to cover up the mistake. Chen Zheng watched with cold eyes for a second and then decisively took back the right to perform the surgery. He completed the extreme hemostasis amid doubts from everyone, shocking the operating room. But the gears of fate have not stopped: under Zhao Hongyuan's comprehensive suppression, he must team up with head nurse Wang Min, mentor Li Bojun and newcomer Su Yao to treat Liu Dahai's rare complications while digging out the shady story of the operation that led to the death of Su Yao's father ten years ago. Changing his life against fate is not the end, what he wants is the innocence of the entire medical system.
