A doctor husband, a smart and handsome son, and an affluent family. Joo-ran's family moves into the 'perfect house' that everyone dreams of. Joo-ran lives in this happy family, enjoying her happiness as her perfect wife, housewife and mother. The only thing that bothers her is the smell from the yard. Joo-ran's husband dismisses it as a manure smell that will soon disappear, but it is hard to erase from her mind like an oil stain on a pretty watercolor painting. This anxiety, which seemed insignificant, grows little by little, and her husband's actions, which seemed perfect, start to feel suspicious one by one.
