Alone and abandoned, Sunbi flees Seoul for the coast in an attempt to reconnect with her past. When she accidentally leaves the train at the wrong stop, she finds herself stranded in a tiny rural village where she encounters a woman full of resentment toward her elderly and decrepit mother. Still plagued by vague, haunting memories of her own mother, Sunbi must find a way to free the woman from the past that torments her-and, in doing so, comes face-to-face with her own demons? Meanwhile, Sunbi's dokebi "husband" Gwangsoo searches for his beloved everywhere, so desperate that he even agrees to join forces with a mysterious stranger who also claims to be Sunbi's groom! Their hunt culminates in a supernatural reunion that raises even more questions about our heroine and her fateful destiny.
