Two more episodes of Takashi Miike's shocking psychohorror mini-series. Chiaki Kuriyama guest stars in 'The Life Constructed in Double Spiral', which finds Detective Amamiya (Naoki Hosaka) and the police team investigating the mass suicide of forty girls from an exclusive private school. Amamiya goes undercover as a teacher to find out why and learn more about a new generation of barcoders, many of whom are students. In 'Smashed Ants', perfectly-severed body parts with numbers cut into them are discovered in a field. In a nearby arcade, two rival youth gangs battle each other - and Amamiya's wife is taken prisoner by a gang leader. The Police Chief tries to put together more of Amamiya's hidden past with the assistance of a one-eyed snuff film maker.
