A man illegally manipulates electrical control systems in offices, buildings, and schools, plunging specific floors into sudden blackouts. Under cover of darkness, when visibility is completely lost, he approaches women, placing a drugged handkerchief over their mouths to blur their consciousness, then proceeds to sexually assault them. This release exposes his actions against five victims: a tall, slender amateur woman, a beautiful office lady, a short-haired J-pop style girl, a glamorous older woman, and more—each caught defenseless and violated one after another. Inevitably, he finishes each encounter with creampie after creampie. In the darkness, no one sees the man's face, adding a mysterious aura that deepens the narrative.
