Creepy chills meet visceral horror and tonsorial madness in this beautifully shot South Korean tale of Ji-hyeon, a young woman who buys her terminally ill, chemotherapy patient sister a nice new wig. After her sister starts making an alarming comeback in mental health to the point of being hostilely aggressive and overbearingly sexual, Ji-hyeon soon discovers the disturbing truth about the history of the wig, which was made from the hair of a cadaver.
