A late-night show crew came to the mountains to shoot exterior scenes. The four of them, host Mami, editor Hayami, photographer Yamada, and publicity officer Yohei, were making a show by the beautiful lake. Suddenly, it started to rain heavily, and the four had to run into a small hotel to take shelter from the rain. The female owner of the small hotel, Reika, was a seductive beauty. The rain stopped at night, and Mami insisted on returning to Tokyo and ran out of the hotel. Hayami and Yohei chased her out, leaving Yamada alone in the hotel. Reika suddenly appeared in front of him, and Yamada couldn't resist the temptation and had sex with her. Unexpectedly, Reika was a witch who sucked people's essence. "Siren X" Hayami and Yohei were so scared by this horrible scene that they immediately drove back to Tokyo and agreed to keep it a secret and not tell anyone what they saw that night. A few days later, Reika came to Tokyo and found Hayami and Yohei.
