Popular horror webcomic artist Ji-yoon finds life imitating her own work when her publisher turns up dead in a way that precisely mirrors the images in her latest comic. Ji-yoon has an airtight alibi, and almost everyone suspects the death was a suicide or a copycat murder. Everyone except the curious detective Ki-chul lets the case languish as a mystery, but when a series of murders that resembles Ji-yoon's drawings occur, he finds himself unraveling the terrifying truth of the comics themselves.
