The Housemaid explores the themes of infidelity, immorality, and regret. Myung-sook, a poor girl who works as a maid, begins working for Dong-sik, a piano teacher. After observing Kim’s lifestyle, she desires the same comfort for herself. She seduces Dong-sik, and he falls for her trap. His one immoral decision destroys his family. When Dong-sik’s wife learns about the maid’s pregnancy, she advises her to abort the baby, as she is more afraid of losing her reputation than confronting her husband.
Myung-sook's character shows the harsh realities of class differences and gender inequality. The narrative illustrates how women from lower-class backgrounds are often subjected to exploitation by those from upper sections of society. Dong-sik believes society will overlook his affair with the maid because of his wealth, but Myung-sook’s obsession and manipulation frighten him. She is portrayed as the villain in the story, although she is also a victim. Her fault lies in desiring a position that does not belong to her, and she attempts to harm others when she feels oppressed or wronged.
The film reflects post-war Korean society and their struggle to embrace modernity, but it also exposes the stigma of higher-class people treating lower-class people as inferior. The movie conveys its message that uncontrolled desires always lead to a destructive path. Momentary pleasures can become a trap that turns into eternal pain. So, living a moral life is the key to happiness.
