Plot
A thirty-year-old housewife, Mi-heun, is visited by a woman in a red sweater. She smirks and tells Mi-heun that her husband is her lover. These few words take away and shatter Mi-heun's life as she knew it, a true terror on an unforgettable Christmas evening.
Swept away by the peaceful, silent town of Butterfly Ville, Mi-heun and her family begin a new life as if nothing had happened. However, the aftermath of that night still haunts Mi-heun with headaches as she vexatiously tries to vent out her heartache, alone. But nothing seems to change.
In-kyu is a not-so-busy country town doctor who enjoys fishing in the nearby lake. The rest of his time is spent on fishing girls out for sex. As the doctor is beginning to enjoy and is getting comfortable with his small town life¡¦he meets her.
