Jo-goo, a street magician (Lee Min-ki), notices a miserable looking girl, Yeo-ri (Son Ye-jin), in the audience during one of his performances, and she winds up being the inspiration for his “Horror magic show.” The show becomes a runaway success almost overnight and Jo-goo in turn, is now a successful stage magician with a model girlfriend. Yeo-ri works for Jo-goo, playing the specter in his show. Forward to almost a year later, the darkness inside her, something her colleagues sense, keeps her from truly connecting with them. When Jo-goo’s attempts to include Yeo-ri in a staff dinner finally succeeds, hilarious disaster ensues when she ends up blindingly drunk. Jo-goo calls Yeo-ri the next morning to sort things out, but when the phone disconnects with a weird sound, he decides to drop by her place for a visit instead. There, Jo-goo meets and engages in a game of hide-and-seek with a ghost child, which then scares the bejesus out of him later that night. As the two of them spend more time together, developing a fast friendship, Yeo-ri confesses the long story behind her gray, wan face.
