Director Tominaga Masanori (Pandora's Box) brings Motoya Yukiko's offbeat play Ranbo to Taiki to the big screen in a juicy, neurotic tangle of love, hate and voyeurism. Hidenori (Asano Tadanobu) and Nanase (Minami) have lived together for ten years in a tense, platonic relationship. The wheels of change are set in motion when married couple Takao (Yamada Takayuki) and Azusa (Koike Eiko) move in next door. After Hidenori catches Nanase and Takao having an affair, he becomes obsessed with watching Nanase through a peephole, and planning his cruel revenge.
