A wealthy family's new maid, Eun-yi (Do-yeon Jeon), attracts the attention of Hoon (Jung-Jae Lee), the man of the house, and a fiery affair develops between them. But although Hoon signs Eun-yi's checks, he's not the one controlling the relationship. One secret leads to another, until Eun-yi threatens to destroy the entire family. This update of the 1960 chiller was an Official Selection of the 2010 Cannes Film Festival.
