Shirley (Lina Romay) ends up in a maximum security prison after shooting her boyfriend dead. Said boyfriend happened to have been a murdering thief who had just stolen millions of dollars worth of diamonds.
Shirley is soon located by a man who is very interested in recovering the stolen diamonds. He watches through binoculars as the story in the prison unfolds. He eventually visits Shirley, but who cares about him anyway?
Inside, the warden of the unusually posh penitentiary wears a black turtleneck, looking like a sort of beatnik Tom Savini. He's a standard pervert out to "help" the female inmates as often as he possibly can.
This is a Jess Franco film, so these inmates are all impossibly beautiful, and constantly seeking out reasons to shed their burdensome clothes. Not that there's all that much clothing to worry about, since the prison uniforms consist of long shirts, high heels, and no pants.
There is, of course, the obligatory torture to accentuate the rampant nudity. The merciless warden likes to watch the whippings like the heinous ghoul he is. He's downright giddy when Shirley is chained to the terrible "hot seat"!
There are also plenty of adult situations that give Franco ample opportunity to... zoom in.
Though dull and talky in spots, this movie still outshines Franco's 99 WOMEN, and the the "turning of the tables" finale isn't bad at all...
