Su Mian had just been transferred to the "Disappearance Department" of the First City Hospital. On her first day of night shift, she received a strange handover form:
——At midnight, you can't look in the mirror.
——At three o'clock in the morning, you must not answer calls from acquaintances.
——When meeting a patient, say "I see you" and leave the ward immediately.
Everyone said that these rules were just to scare newcomers, but Su Mian saw with her own eyes that the previous night shift nurse answered the phone at three o'clock and disappeared from the surveillance camera.
She is a top forensic doctor and knows how to perform autopsies and anatomy, and she also knows how to see the secrets in people's hearts.
When the rules were triggered one by one, she discovered that behind them were a series of man-made "accidents" - someone was using the rules to cover up the truth.
Every time she breaks a rule, she gets one step closer to the real murderer and one step closer to being exposed...
