Synopsis

Kim Tae-yong and Min Kyu-dong direct this thriller about teen sexuality and supernatural fury.

The film focuses on the young nubile Min-ah (Kim Min-seon), who stumbles upon a diary/scrapbook that details the freakishly intense relationship between her schoolgirl classmates Shi-eun (Lee Yeong-jin) and hacket-faced Hyo-shin (Park Ye-jin). The pair seem to have some sort of telepathic bond.

When Hyo-shin appears to commit suicide, Min-ah shows the diary to two of her friends and the three attempt to discover what really happened to the girl.
