The popular Shimada family's eldest son, Naoto, invites his seminar friend Yamada to his home.

Under his influence, Naoto's sister, younger sister, mother, girlfriend, and the entire family fall under hypnosis, transforming into depraved versions of themselves. This terrifying story unfolds as everyone dear to him is dominated by hypnotic rays.
