A female delinquent detective discovers an apocalyptic plot by a nefarious underground website in director Kenta Fukasaku's take on the popular serious previously adapted for the screen in film, television, and anime form. Asamiya (Aya Matsuura) is a tough New York City street kid who doesn't take kindly to authority figures. When Japanese officials discover a cryptic but undoubtedly sincere threat from a website known for offering tips on committing suicide and constructing bombs, they immediately have Asamiya whisked back to Tokyo, trained by the police force's special operatives unit, and placed under the care of stern Kazutoshi Kira (Riki Takeuchi). With few clues to go by and only 72 hours to spare, Asamiya must venture into Seisen High and wield her deadly yo-yo against a dangerous group who seems all too determined to set the city ablaze.
