But the master, Mr. Hoon, was different. He noticed her. Not with the lecherous gaze she expected from Korean dramas, but with something worse: empathy.

The narrative centers on Eun-yi, a young woman of humble means who secures employment as a live-in maid for a wealthy industrialist family. The setting is crucial to the film’s thesis: the family resides in a lavish, palatial home that feels less like a sanctuary and more like a fishbowl. The architecture is defined by towering glass walls, steep staircases, and cold, sterile interiors. This environment is an extension of the family’s psyche—isolated, untouchable, and transparent only when it serves them. For Eun-yi, the house becomes a gilded cage. The glass walls symbolize her lack of privacy and her status as an object to be observed and consumed by the male gaze of her employer, Hoon.

Some stains don't wash out.

The film’s central conflict ignites when Hoon seduces Eun-yi. In a typical Hollywood thriller, this might be framed as a romantic tryst or a steamy affair, but Im Sang-soo frames it with a disturbing sense of inevitability and coercion. The power dynamic is heavily skewed; Eun-yi is not a partner in this romance but a tool for Hoon’s boredom and entitlement. This dynamic exposes the film's core Marxist critique: the wealthy do not merely purchase labor; they feel entitled to the bodies and souls of those they employ. When Eun-yi becomes pregnant, the fragility of her position shatters. She is no longer just a servant; she has become a liability to the family’s lineage and reputation.

Then came the night of the anniversary party. The madam drank too much champagne. The grandfather—a paralyzed patriarch in a wheelchair—watched Eun-ha with the stillness of a spider. And Hoon, drunk on soju and loneliness, placed his hand on her waist in the pantry.
