由三原光寻导演、嘉门洋子等主演的一部惊悚悬疑类影片。本片改编自日本著名推理小说家江户川乱步的同名小说,反映的是对偷窥者和谋杀的研究,并以爱伦·坡式的恐怖故事的味道传达专横跋扈的变态情欲。本片将原来的男性“散步者”乡田三郎设定为死者,大胆改用女性来做偷窥者和受害者,以她的行动和遭遇来推动情节的发展,同时也使得片中有着浓郁十足的香艳气息。Private detective Kogoro (Kouta Kusano) receives a request from Naoko (Yuki Mamiya). She is the daughter of a family that runs a large hosital. Naoko wants private detective Kogoro to investigate her fiance Endo (Yasushi Fuchikami) and whether he is having an affair with university student Teruko (Noriko Kijima).
