  The Housemaid (2010) / Hanyo 

Warning : Contains Adult Content

Poor divorcee Eun Yi, gladly signs on to work as a nanny and housemaid for a wealthy, upper-crust family. In her naive eyes, the rich and handsome Hoon (Lee Jung Jae, Typhoon), his pregnant wife Hae Ra (Seo Woo, Paju), and adorable daughter (Ahn Seo Hyun) make the picture-perfect family. But that myth is soon shattered when the domineering Hoon finds his way to her bed. Their torrid affair upsets the balance of the household, unleashing a cruel power struggle as Hae Ra, her mother (Park Ji Young), and the head housekeeper (Yoon Yeo Jung) all answer with their own calculated measures.

A highly anticipated remake of Kim Ki Young's 1960 classic, which is widely regarded as one of the best Korean films ever made.
