Ryuichi Koga (Sonny 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 Satô), 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'er-do-wells as each come to question each other's motives.
