Scalpel and Heartbeat

During the emergency rescue at three o'clock in the morning, emergency doctor Su Qingyan frequently interacted with the mysterious patient Lu Shiyan who claimed to be "deceased". This police officer who "sacrificed" during an anti-drug operation three years ago is now using band-aids to heal stray cats and using old photos to awaken her dusty memories - the rescue of a university laboratory fire, the fatal coincidence of a truck on a rainy night, the contradictory medication records in the medical record, and the unsent "Target Abnormality" text message on his mobile phone, all tearing at Su Qingyan's cognition.
