Hyun-woo, a blind street performer, sings inside an underground market in Seoul. One day, a man tells him about the murder he said he committed but later says that he was only talking about a novel he's writing.

However, people Hyun-woo knows keep disappearing, and they end up being identified as victims of a serial killer whose method is identical to the one Hyun-woo heard from the man.
