Lin Shuyue is a criminal profiler specially hired by the provincial department, and she is also a latent empath - she can sense the murderer's psychology by touching the evidence. This talent allows her to repeatedly solve strange cases, but it also allows her to forget fragments of memories after empathizing. Until she met Jiang Yanshen, the criminal investigation captain whose right hand was permanently trembling, she discovered that her memory loss was closely related to his father's death in the line of duty.
Jiang Yanshen is an expert in micro-expression recognition and has been lurking in the Golden Triangle for three years. The tremor of an old injury in his right hand is his deep secret and the shackles that prevent him from pulling the trigger. When he discovered that the old marks on Lin Shuyue's body were consistent with the marks on the unsolved case twenty years ago, he realized that this might be a game of truth across time and space.
A series of bizarre murders involved the two people in the whirlpool of memory. The burning flames in the bride's self-immolation case, the secret clues in the dusty old things, the code names written in the music box... Each case reflects their broken past. When Lin Shuyue reveals her connection with the old case, and when Jiang Yanshen faces the truth about his father's death in the line of duty, they must piece together the fragments of memory and redeem each other's souls at the edge of the abyss.
Concept: When memory becomes a murder weapon, only a broken soul can piece together the truth
