a South Korean horror movie. Mi-ju is not having a very good life. For one, sheâÂÂs no longer in love with her job teaching cello to a bunch of spoiled brats, one of whom holds a grudge against her and may be trying to run her over with a car. At home, Mi-juâÂÂs oldest (and very strange) daughter is learning to play the cello, and doing a terrible job of it. And then thereâÂÂs her amazingly uncharismatic fiancâÂÂ, who just hired a housekeeper who may just be the creepiest housekeeper to ever go into business of cleaning house. Plus, the cello her daughter is playing seems to be haunted.
