A man's affair with his family's housemaid leads to dark consequences.

Eun-yi is a playful young woman, a good match for a job as nanny to a precocious child, Nami, the daughter of a wealthy couple, Hae-ra and Hoon. Hae-ra will soon have twins as well. The majordomo, Mrs. Cho, is the household's cold stone center. Before long, Hoon seduces Eun-yi, and when Mrs. Cho tells Hae-ra's mother about the affair, Eun-yi is up against women with wealth, power, and no conscience. Can Eun-yi maintain her dignity and perhaps even put the family in their place?—<[email protected]>

Mrs. Cho, the majordomo for wealthy young couple Goh Hoon and Goh Hae-ra, dislikes her job. She treats it in a cold, straightforward fashion, while slyly tries to take whatever advantage she can out of the Goh's lavish lifestyle. Because Hae-ra is pregnant with twins - which would be the Goh's second and third children - Mrs. Goh is tasked with hiring a housemaid whose duties largely would be to take care of the Goh's young daughter, Nami, help Hae-ra with the pregnancy, take care of the twins when born, and cook and serve meals. Mrs. Goh hires Lee Eun-yi, a young woman who works at a street food stall. After being ensconced in the job and the household, Eun-yi, who likes the job, succumbs to Hoon's sexual advances, the two who begin an affair directed solely by Hoon, and which results in Eun-yi getting pregnant. All the adult women of the house - Hae-ra, Hae-ra's mother, and Mrs. Goh - end up finding about the affair and the pregnancy. Each of the three has a slightly different reaction to the news, and what they believe they need to do to restore what was the on the surface family harmony. In turn, Hoon and more importantly Eun-yi, have their own responses to what is happening in the house.—Huggo
