Suzuki is the master! He has made the greatest examples of 60's low budget exploitation cinema. The way he uses a different color to represent each of the prostitutes almost makes them appear like demons in that underground lair of theirs. But who is the real monster of the film? The occupying Americans who use the prostitutes? The prostitutes themselves? Or is it the hate filled ex-soldier (played by the great Joe Shishido!) who controls the women?
