Ten years ago, in the "Red Dress Case" in Qinggang, five women wearing red dresses were murdered one after another, and the murderer is still at large. The fifth victim is the sister of Shen Yan, the leader of the serious crime team.
Ten years later, similar bodies reappeared. Beauty blogger Lin Wanwan died in her bathtub, with her red dress floating, a smile on her lips, and lipstick written on the mirror - "You are next."
Shen Yan chased the murderer for ten years and hated himself for ten years. Until Gu Nian, a criminal psychology expert, parachuted into the task force - she could "see" the residual emotions of the murderer and the deceased at the crime scene. One is a tough detective who bears the blood debt of his sister, and the other is a genius profiler who can empathize with death. From mutual questioning to life and death dependence, every case is like a mirror, reflecting the deepest undercurrent of human nature.
But Gu Nian also has a secret of her own - when she was seven years old, she saw her mother being killed. The murderer has not yet been found.
Two people with old wounds traveled between the "Red Dress Case" ten years ago and the serial murders in front of them. The more they investigated, the more they discovered: all the deaths pointed to the same name. That name has been watching them from the dark for a long time.
Volume 1: Girl in the Mirror: A beauty blogger said in a live broadcast three days before her death - "I know more about the truth about the red dress case than you do.
