The Uninvited

“There is more to this world than is safe to know…”

Jeong-won (Park Shin-yang), an interior designer about to be married, watches two small girls sit down on a subway train and die there. He sees them again in his apartment, and the only person who can see them too is Yeon (Gianna Jun), a woman he meets by chance. Lee Soo-youn follows the two of them as Jeong-won tells her about a childhood he can't remember, the girls waiting where they were last seen.
