Yumi and Misa are high school classmates. Both now 30 years old, Yumi is married while Misa remains single. The reason? Back in school, Yumi introduced Misa to lesbian pleasure, awakening desires that made Misa fall exclusively for women. Still deeply in love with Yumi, Misa seizes the opportunity of a long-overdue reunion to carry out a secret plan: getting Yumi drunk and disoriented before making her move. Lost in nostalgic memories and slowly losing awareness to alcohol, Yumi unknowingly falls right into the center of Misa's seductive scheme.
