The film was originally licensed by Central Park Media and then later licensed by ADV Films. The story involves the town of Kabuki-cho, home of a resistance faction called Messiah. In the futuristic setting, Kabuki-cho is one of the last places of freedom because the Persona Century Corporation has taken control of the majority of the Earth.
