This fourth film in the series which began with Joshu 701-go Sasori (1972) almost didn't get made because star Meiko Kaji was tired of her role. Toei Studios coaxed her back by replacing Toshiya Ito -- who made the first three films -- with Yasuharu Hasebe, who had directed Kaji in Naraneko Rokku: Onna Bancho (1970) and two of its sequels. Scorpion (Kaji) escapes from jail and ends up on the run from some thuggish cops. She finds a haven with a former college classmate who works backstage at a strip club. Scorpion tells him about her unfortunate adventures, later conspiring with him to finally expose her ex-boyfriend, the crooked vice cop whose attempted murder had resulted in her initial arrest. This was the end of the series for all practical purposes, although Yutaka Kohira directed a pair of sequels starting with Shin Joshu Sasori: 701-go (1976), each starring different actresses in the lead.
