The rift in a perfect marriage began with a bloody pearl.
Former forensic doctor Lin Wanqiu found a photo in her husband Chen Mo's study: a woman wearing a pearl necklace collapsed in Jingquan Square, and blood stains snaked on the ground into a strange smiling face. What chilled her even more was that the necklace around the deceased's neck was exactly the same as her wedding token - until she found the laser-etched number "7" in the pearl buckle, she was shocked to realize that it was the murderer's "trophy number."
Smart home surveillance recorded "her" carrying a bloody suitcase late at night. Scalpels, sedatives, and forged diaries, all evidence pointed to herself. But as a former criminal forensics expert, she knows better than anyone else: the direction of the fingerprints, the angle of the blood spatter, and the walking habits of "herself" in the surveillance are all revealing a horrifying truth - the person beside her is using marriage as a cocoon to trap her in a carefully woven mirror cage.
When her daughter's flashcards, the baking scale in the kitchen, and the audio from the driving recorder gradually became the key to cracking the password, Lin Wanqiu gradually pieced together Chen Mo's dual identity: on the surface, he was a gentle and considerate CEO of a medical company, but in fact, he was a serial killer suffering from emotional mirroring disorder. He marked his prey with pearl necklaces, used smart home systems to tamper with memories, and carried out bloody organ transplant transactions under the mask of a "perfect husband."
In the court, she used forensic powder to develop the fingerprints deliberately left by her husband, and used the metal chip in the pearl drill hole to expose the surveillance control. When Pearl No. 7 Broke in the witness box, not only the bloody truth came out
