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

In a luxurious house outside Seoul lives one of the country's richest families: company president Yoon, his wife Baek Geum-ok, their divorced daughter Nami, and son Chul. Yoon is company president but the reins of power are held by his wife Geum-ok, whose aged father was once a powerful businessman, and whom Yoon married for her money and influence. Yoon's private secretary is Joo Young-jak, from humble origins. His current job is making sure a U.S. businessman, Robert Altman, is kept happy with Prostitutes, as part of a major business deal that could prove crucial to the family's fortunes. When Geum-ok sees Yoon having an affair with their Filipina maid, Eva, on her hidden CCTV, she beds Young-jak in revenge. When Chul is arrested for organizing a slush fund for Altman, Geum-ok decides to further punish her husband for his "mistake" in bringing the family's name into public disrepute, by having Eva killed. At the same time, Nami and Young-jak, start an affair. Yoon commits suicide over Eva's death (and takes the blame for his son's activities). After his funeral, Young-jak quits the family, glad to be rid of their influences. He accompanies Eva's coffin to the Philippines, where he is joined on the plane by Nami.
