I can always "see" the last image of the deceased and use it to create a picture of the killer. This talent has made me a secret weapon in the police department, and it has also brought me to the verge of collapse after every empathy. Until I was assigned to the notoriously ruthless criminal police captain Chen Jin. He questioned my abilities and even more disgusted with my "fragility." We are forced to team up to hunt down a serial killer who specializes in killing "pretenders." When I tremblingly drew the outline of the murderer, only to find that it was somewhat similar to Chen Jin, he put out the cigarette butts and his eyes froze: "Teacher Lin, am I the one you want to draw next?" The relics at the crime scene stung my fingertips, and new scenes of death flooded into my mind - this time, I saw myself when I was young, and Chen Jin's old partner lying in a pool of blood. It turns out that our past has long been stitched together by the same crime. And the only way to unravel all this is for me to have one last fatal empathy with him.
