During a bank robbery on a rainy night, only half a silver ring with a special pattern was left behind in the surveillance camera. This was the "ghost robbery" that the criminal police captain Yan Chixu had been pursuing for three years. The only new clue pointed to Wen Yan, a criminal psychologist who suddenly returned to China.
The two met tit for tat for the first time: Yan Chixu was cold and sharp, accustomed to using evidence to uncover the truth, but his rhythm was always disrupted by Wen Yan's seemingly careless profiling; Wen Yan was lazy and casual, always drawing on key points in the case file with the pen between his fingertips, and there was an unknown undercurrent hidden in his eyes.
As the investigation deepened, they discovered that the silver ring was actually related to an unsolved case ten years ago - in that case, Yan Chixu lost his partner and Wen Yan became the only survivor. When the robbery happened again, the handwriting left at the scene was highly similar to Wen Yan's notes, and trust instantly collapsed.
Is it a carefully laid plan by dormant criminals, or are the people around you hiding deadly secrets? Yan Chixu clutched the blood-stained silver ring and looked at Wen Yan's back as he turned away. For the first time, he hesitated on the way to pursue the murderer: Is the person he wants to catch the murderer, or the person who hides behind the truth and makes his heart beat?
Philosophy: A ten-year-old case is entangled, and the pursuit of the murderer is intertwined with doubts.
