Goku, the lone wolf private detective is back, contracted by Yoshiko, a mysterious, beautiful and very afraid woman, to find and save her brother, Ryu. Will Goku be able to protect Yoshiko from her step father's soldiers long enough to find her brother? Meanwhile Ryu, the unfortunate subject of a military experiment gone bad, leaves a trail of bodies behind him and has no intention of being found or saved by anyone. Will Goku have to kill the man he is supposed to save? Will even his omniscient cybernetic eye and sceptre be enough to help him defeat this indestructible killing machine?
