Shen Yan, a member of the Beijing Major Crime Team, is crazy, ruthless and tough. He doesn't believe in ghosts and gods, he only believes in evidence.
Until criminal consultant Lu Shiyan was parachuted in.
He has a photographic memory and can reconstruct the murder scene from clues, but he hides a fatal curse-the memory can be tampered with.
On a rainy night in the old alley, his memory "saw" the murderer for the first time: the tall back, and the obsidian ring on the ring finger of his left hand that was exactly the same as Shen Yan.
Since then, serial murders have continued, and all clues point to Shen Yan. Lu Shiyan is repeatedly pulled between the testimony of his memory and the love in his heart.
Do you believe in memory or your lover who fights side by side?
As the investigation deepened, an unjust case from ten years ago came to light. Lu Shiyan finally discovered that his memory had been deliberately manipulated since childhood, and the real murderer had been using his hands to frame Shen Yan.
In the end, he broke away from the memory trap and teamed up with Shen Yan to find out the mastermind behind the scenes, completing redemption and staying together.
