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 fishing girls out for intimate. As the doctor is beginning to enjoy and is getting comfortable with his small-town life, he meets her.
As Mi Heun sits blankly under the blazing sun at a rest stop, a sharp voice comes to her like an alarm and awakes her. She refuses him with all her body and might, but at the same time, falls into him with her entire body and soul.
In Kyu gives Mi Heun an overwhelming answer to her question. When she felt like she was at the end of her ropes, she falls into a dangerous game of intimate that would never allow for love. Unaware of herself, she starts to enjoy the lover’s game more and more.

However, the one person who should be there sharing his small dream is not there. The lonely pond remains as Mi Heun is walking through the heavy woods that are found outside the only motel in town. What will become of the husband who waits for his wife, and the two star-crossed who choose the path of no return? Is there an end to their never-ending desires?
