Married for 13 years, Reiko has no children and works at a family restaurant during the day. One morning, she woke up to find countless rope marks etched into her body. Unable to discuss these unfamiliar marks with her husband, she was gripped by fear. Then, a few days later, her coworker Tomita tells her something unbelievable. Reiko vaguely recalls drinking with Tomita the night before the marks appeared. 'That wasn't a dream? Could it be you... you tied me up...?'
