Impulse Pictures is proud to present THE NIKKATSU EROTIC FILMS COLLECTION, a continuing series of critically acclaimed classic "eroductions" designed to shock and titillate fans of Japanese erotic cinema. One of the more sadistic entries in the Impulse Pictures Nikkatsu series, ASSAULT! 13th HOUR pushes the sexual violence boundaries in cinema as far as possible. A violent sexual predator (named "Crimson") takes on a young protégé, and they are both pursued by vengeful gangs of vigilantes hellbent on capturing the pair for their crimes. As the two men evade the law, they continue their violent assaults on various women of the community. Will the authorities ever catch this disgusting duo, or will they suffer a much worse fate at the hands of the gangs looking for brutal revenge?
