On the surface, "The Servant" appears to be a straightforward tale of a servant and her employer. Mi-nyeo, a poor and vulnerable young woman, is hired by the wealthy and influential Park family to serve as their maid. However, as the story unfolds, it becomes clear that Mi-nyeo's intentions are far from pure. She begins to manipulate and subvert the traditional roles of servant and master, gradually assuming control over the family and turning their lives into a living nightmare.
