You know where you stand with this film inside five minutes, from the moment policewoman heroine Mika Hino (Shiratori) is made to strip off by bad guys hunting for a key -- which she naturally is keeping in her lingerie. Mind you, this pales in comparison with where partner Rin Kakura (Kuribayashi) hides her gun...

Mika Hino is a sharp-shooting investigator that belongs to the infamous "Gator Branch.” When an executive board member of a trading company is accused of being involved in a bribery, Mika is assigned to keep watch over him.

Once again we focus on Nami Matsushima. This time she has a sister who goes missing and after getting too caught up in doing something about it, our innocent heroine is given a fifteen year sentence for a murder she didn't commit. She's sent to an all women prison where she's not exactly welcome. Her fellow inmates torture, humiliate and try to kill her; but the Scorpion prevails long enough to get some justice.

Nami Matsushima, a former doctor, is put in prison for murdering one of the men who raped and killed her sister. Now, faced with violent and lecherous prison gangs, an aggressively amorous warden, and with a friend on death row, Nami must steel herself for a ten year stay in one of Japan's toughest women's prisons.

Nami Matsushima has escaped from the prison to which she was sentenced in Scorpion, but is now obsessed with tracking down the--don't laugh--one-armed man who murdered her younger sister fifteen years ago. Nami is certainly no great action heroine, and the plot at times makes little sense, climaxing with a coincidence more ridiculous than any Shakespeare ever used. For complicated reasons, Nami uses her medical knowledge to break into a women's prison as staff physician. There, as in the previous movie, the convicts wind up naked awfully frequently.
