Cold-faced anesthetist Shen Zhao was publicly divorced by her ex-husband Jiang Xu's family, and his reputation was ruined overnight. Five years later, Jiang Xu suffered a sudden aortic dissection, and when he was about to die, he named her for anesthesia. She coldly accepted the appointment and saved his entire family on the operating table: his seriously ill father, the illegitimate child he had hidden for ten years, and his ambitious current wife—all involved in a serial infection crisis. When the old scars are opened by blood and electric knife, this life-threatening rescue truly begins.
