At three o'clock in the morning at the abandoned fertilizer factory, the silence of the city was broken by the body parts rolling down from the mixer. Lin Lan, the female criminal police captain, rushed to the scene with exhaustion from three weeks of sleeplessness. Amidst the smell of rust and blood, a broken heart-shaped pendant engraved with "L" and "Y", embroidered fabrics from Italian luxury brands, and fragments of high-end custom perfume were pieced together to piece together the mysterious identity of the victim.
The shadow of the death of his partner three years ago has not yet dissipated, and Lin Lan is plunged into this difficult murder case. Forensic experts determined that the body parts had been frozen, and the traces of deliberate cleaning at the dumping site revealed the murderer's calmness and haste. As the investigation deepens, consumption records in luxury brand stores point to the missing investment company vice president Su Wan, while the couple necklace she wore and the special fiber residue in the apartment point to the mysterious doctor boyfriend Lu Yu.
When the chimney of an abandoned factory casts an abyss-like shadow in the morning light, and when the victim's perfect life is torn apart by cracks under the luxurious appearance, Lin Lan discovers that behind the case of mutilation, not only is there a twisted emotional entanglement, but there is also a dark secret that can subvert everything. Every clue is like a tangled vine. On the road to chasing the truth, she must face the trauma of the past and the dangers of reality, and find the gap leading to the light in the puzzle weaved by the murderer.
