A beautiful cellist attempting to regain stability after surviving a car accident that claimed the life of her best friend finds that her troubles have only begun when her personal life takes an ominous turn for the worse in director Lee Woo-cheols harrowing tale of psychological horror. Physically bruised and mentally scarred, theres nothing that Mi-ju (Seong Hyeon-ah) wants more out of life than to let her recently departed friend rest in peace and heal from the pain of her past. When the memories of the accident become too powerful to bear and Mi-ju decides to forego her professional music career in favor of teaching cello to both her daughter and the students at a nearby university, the horrors of her past prove nothing compared to the terror that slowly begins seeping into every aspect of her quiet existence. As the music that drifts from her daughters instrument begins to take on an ever more grim and unearthly quality, Mi-ju attempts to maintain some semblance of sanity after being attacked by a vicious student, trying to make sense of her sister-in-laws dangerous obsession with her fiancé, and struggling to pinpoint just what it is about her new housekeeper that makes her so uneasy at times. ~ Jason Buchanan, All Movie Guide
