The notorious 1970's women in prison classic. Taking a cue from Don Edmond's classic Ilsa: She Wolf of the SS, Helga moves the action to South America, where she lords over a castle of female political prisoners, who are stripped and tortured at whim, until local rebels help them fight back against their captors and attempt escape. Nudity, violence, fetishism and lesbian catfights - what more could you ask for?
Stilberg is a ominous fortress which has been turned into a detention camp for political prisoners, under the command of Helga Stiver, an ardent follower of the party in power where she brutalises the female prisoners. Lisbeth, the daughter of the opposition leader arrives at Stilberg where she, too, falls prey to the sadistic Helga.
