In a monochrome Japanese city of eternal rain, a repressed phone counsellor (Asuka Kurosawa) is sent a sheaf of photographs that show her masturbating. She is contacted by a terminally ill ex-client (director Shinya Tsukamoto), who threatens to send the photos to her overbearing husband (Yuji Kohtari) unless she walks about in public wearing a miniskirt with an internal vibrator whose remote control he has.
This whack-job premise kinks into even odder areas, hinting at a world akin to that of Tsukamoto's Tetsuo films. The husband is abducted by the oddest cult ever put on film, the heroine unpredictably responds to her long-distance tormentor/saviour, and Tsukamoto sprouts a Meccano-style penile extension to throttle Kohtari.
