On a stormy night, a corpse turns up in a luxurious mansion. Young forensic pathologist Qi Yan clashes fiercely with Detective Captain Wei Sheng over her precise autopsy findings, yet secretly pockets a crucial piece of evidence while processing the scene: a bloodstained sapphire cufflink.
That deep blue strikes at a nightmare buried for twenty years. Her father, a jewelry appraiser, died in an unsolved murder. As a string of killings unfolds, every victim turns out to be connected to her father’s old case, and Qi Yan’s fingerprints are found on the murder weapon.
To prove her innocence, she is forced into a dangerous alliance with Wei Sheng, the man investigating her.
He is sharp as an eagle, yet caught in the middle of a suspension crisis. She is cool as ice, yet trembles because of her claustrophobia.
Through deadly confrontations in an abandoned factory and the piecing together of clues in an underground chamber, the two gradually uncover each other’s scarred pasts.
But the Blue Heart Society’s shadow has already seeped into the upper ranks of the police. Every step closer to the truth makes Qi Yan a target.
When the code hidden in the long-buried gemstone is cracked, it points to the shocking possibility that her father may still be alive. A deadly trap is already closing behind her... Evidence can lie, but corpses are always honest.
But if even her closest family is part of the mystery, should she trust the truth beneath her scalpel, or the instinct in her blood?
It's like watching a fairy tale! 😜
