Genius forensic doctor Shen Zhiyi witnessed her husband Li Yanchuan being involved in a secret room murder case on their wedding night. The autopsy report and the evidence at the scene contradicted each other and directly implicated him. In order to prove their innocence, the couple who made the agreement were forced to start the "night-time crime solving" mode - during the day, she was a forensic expert who calmly dissected the truth, and at night, she transformed into a "sweet wife detective", using intimate contacts to obtain clues, and using daily life in marriage to cover up the investigation. When corpse dismemberment cases, serial poisonings, and AI face-changing scams happened one after another in the wedding room, Shen Zhiyi discovered that the murderer was always imitating her method of dissecting corpses. Li Yanchuan appears cold and tough but secretly protects his wife. The two gradually develop a true love during the bloody investigation, but they reveal an even more horrifying truth: all the cases are "perfect crime teaching" designed for Shen Zhiyi, and Li Yanchuan's "suspect" is the last mystery left by her missing father ten years ago.
Intention: 1. The game between truth and emotion. 2. The symbiosis of light and shadow. 3. The closed loop of redemption and inheritance
