Followed by the death of her friends, journalist Hong Sun-Joo comes across a videotape containing incomprehensible images. Towards the end of the tape, she finds the curse which states that the viewer would die at the same time next week if he/she does not perform certain tasks. However, the next scene explaining the nature of the task has been erased. Sun-Joo and a doctor named Choi-Yul embark on a journey to break the curse placed upon them. They discover that the videotape was made by the psychic called Park Un-Seo. Un-Seo was an illegitimate daughter of a female psychic and was born a hermaphrodite. She was romantically involved with her half-brother and worked in a night club for a while. There, a man who found out about her secrets was killed as she had the uncanny ability to protect herself. The video tape is the medium Un-Seo uses to reveal herself to the society. Her first exposure to the media was a painful experience, which caused her to withdraw from the outside world. When it became difficult for her to relate to the society, she retaliated by infiltrating it like a virus. The way of infiltration is one-way only and any attempt to block the process ends in extremely negative consequences.
