In keeping with much of the "pink revolution",time has not been kind to this early 70's bout of subversiveness but the trilogy is not without its compensations.
Meiko Kaji is excellent as the titular heroine who in the first installment Female Prisoner #701:Scorpion is framed by her corrupt cop lover and ends up in prison where she is subjected to all manner of degredation but will not break no matter the provocation and escapes to avenge herself on those she holds responsible for her incarceration.
In the sequel Jailhouse 41 we find Scorpion back behind bars but after securing an escape with some other inmates we are treated to her own particular brand of justice.
In the final and best of the trilogy Beast Stable, Scorpion is at large hiding out from the police and befriending a prostitute Yuki whose own life incorporates having sex with her brain damaged older brother and whose "friendship"allows Scorpion to exact a fitting revenge.
Shunya Ito directs all 3 parts and the first has many striking moments amidst a fairly familiar movie prison environment,Ito throws the kitchen sink at the second with supernatural elements,dream sequences and wild colours which only seem to get in the way but the final part has some real bite with a nicely lurid and balanced narrative with many striking scenes.You will not forget Yuki in the grave yard turning to see Scorpion chewing on a human arm in a hurry.
That said,Female Prisoner is by today's standards fairly tame with only part 3 really holding up in it's violent subversiveness but what does hold up is Kaji as Scorpion whose pact with Ito to have Scorpion say as little as possible works wonderfully well.Kaji is delightfully enigmatic as a result and her homicidal outbursts are deliriously played out to punctuate her deep rooted sense of injustice.
Worth it for Kaji and Part 3.
