Touching the jade pendant of the Republic of China with her fingertips, Shen Yanning felt a sudden stabbing pain in her neck. In 1941, the rain seeped into the studio. In the mirror, she was wearing a military uniform and raising a knife towards him. The cracks in the memory of the officer with the word "Gu" on the badge were exactly the same as the jade pendant in his hand.
As a descendant of a treasure protector who has been stigmatized as a "collaborator", her "antique synesthesia" is bloody: she tastes suffocation when touching costumes, feels bleeding from all her orifices when touching a blue and white vase, and the memory of the Republic of China invades reality step by step.
"How come the Republic of China ink on Miss Shen's sleeves is consistent with the murder scene?" Sheriff Gu Shiyan came with a pocket watch, which contained half a picture of cultural relics. The word "Ning" matched her jade pendant - he was investigating the grievances of his grandfather, and also pursued the case of his father's disappearance ten years ago. "Don't trust the Shen family" turned the encounter into a life-or-death test.
The owner of the troupe was killed while sewing costumes, and fluorescent powder pointed at her; the auctioneer died suddenly while holding a blue vase, and the phantom of his grandfather advised him to "don't believe her." She was shocked to realize: Wen Jingzhou who delivered the medicine was the descendant of an informer, her best friend Meng Qingli's father was the mastermind of the theft, and the police force forced her to surrender.
The bell of the clock factory rings, and Shen Yanning falls into the year 1941: his grandfather and his father are hiding cultural relics, and her grandmother seems to hear sounds from the future. Is memory across time and space a key or a trap? The truth will be revealed in the secret room of the old house - her "guarding across time and space" ability has destined her to meet him eighty years later.
