The film opens with a young woman committing suicide by jumping from a building ledge. Eun-yi, who works in a restaurant, persuades her coworker and roommate to drive her to the scene of the suicide, and she stands distraught over the chalk outline where the woman's body had lain. The next morning, an older woman named Byeong-sik visits her small apartment and later expresses interest in giving her a job. Eun-yi is hired as an au pair for Hae-ra, who is pregnant with twins, and her rich husband Hoon. Eun-yi's primary task is watching the couple's young daughter, Nami. Hoon begins to secretly flirt with Eun-yi, enticing her with glasses of wine and his piano playing, and they eventually begin a sexual relationship. Despite the affair, Eun-yi is still warm and friendly to Hoon's oblivious wife, Hae-ra; she even expresses enthusiasm and delight at the progress of Hae-ra's pregnancy. As the story unfolds, the women of the family plot against Eun-yi, who must fight an equally devious battle to protect herself.
