One night, after tennis practice, she is brutally assaulted in the locker room shower by a man with a stocking over his face. Left on the floor naked and in shock, she discovers a single puzzle piece left behind by the crazed man. A few days later, a pair of students enact a perverted sexual revenge on Reiko for kicking someone off the tennis team. Could one of these students be the man who brutalized her in the locker room? Who owns the strange puzzle piece? As the mystery unfolds, Reiko must come to terms with her own sexual urges and fate.
