Fists flurry and blood flows as legendary cult director Teruo Ishii (HORRORS OF MALFORMED MEN) joins forces with martial arts legend Sonny Chiba (THE STREET FIGHTER) in this bone crunching karate classic from Toei. Ryuichi Koga (Chiba) is a descendent of the Koga Ninja school, now earning his living through more nefarious means as a gun for hire. When he is enlisted to take down a drug cartel alongside Hayabusa (Makoto Sato), a disgraced former narcotics detective now operating within the criminal underworld, and renegade Aikido master Sakura (Eiji Gō), tensions grow among this three man team of ne'erdowells as each come to question each other's motives.
