Su Chen, a professional "special scene cleaner", works to restore haunted houses, murder scenes, and accidental death sites to their original state, as if nothing had happened. But he has a secret: he can sense the last remaining "story" on the object through touch.
This ability is both a curse and a gift. He is forced to "watch" countless moments of despair, fear and madness until he cleans out a luxury apartment that the police conclude is a "suicide." When his fingertips touched a neglected music box, a memory fragment that did not belong to the deceased and was filled with violence and panic flooded into his mind.
Behind the conclusion of "suicide" is a perfectly arranged murder.
When the silent objects begin to whisper, the outline of the truth gradually becomes clear in the blood and lies. This is the story of a man who makes a living by "collecting corpses" and "picking up garbage", and is forced to become a crime terminator in the urban reinforced concrete forest. He just wants to clean up quietly, but these "evidences" always have something to say.
