Yumi, a writer of a science magazine, witnesses a mysterious death of a high school girl who received a "one missed call" from her own cell phone, two weeks in the future. The disturbing message on the cell phone turns out to be the screams of the victim.

The script won the 2006 TV Asahi contest for new scenario writers. The story is about the secret game between two childhood friends. In that game, Kurokawa is a princess and her friend Mizushima is her servant. They promised to keep on playing the game until someone finds about it.

Toshiko, a high school student, receives a text message and picture from her brother, whom she has not seen in years. The image foretells the death of a woman a day later. This is only the first of many haunting images that appear throughout the film.
