Genius doctor Cheng Yao was expelled from the hospital for exposing medical corruption. His left arm was seriously injured and he was saddled with a blood debt. Three years later, he brought a stack of medical records and smashed the luxurious wedding banquet of the dean's daughter, making the darkness public. Lu Zhao, his former subordinate who had betrayed him, had a recording in his hands. Chen Xiu, a terminally ill nurse, was still secretly recording incriminating evidence, and Shen Zhiyao, the daughter of the dean, took the initiative to hand over key evidence. A revenge that uses medicine as its blade and medical records as bullets is spreading from the bloodstains in the emergency room to the center of power. What Cheng Yao wants is not to be reinstated, but to have every forgotten medical record become a testimony in the trial.
