of ILSA's private quarters. Here ILSA, assisted by her two henchwomen, Ingrid and Margrit, hope to prove by subjecting women to the most excruciating forms of torture and punishment, that women are equal to men when it comes to standing pain. ILSA is an Aryan who can stand no weakness in either women or men. To satisfy her tremendous sexual appetite, she sleeps with one of the male prisoners each night, and then castrates him if he cannot satisfy her. in the camp, she is known as the "Black Widow".

So thoroughly has she intimidated the prisoners of "Camp 9", they cannot even begin to think of escape. All this changes, however, when a new shipment of prisoners arrives. Even before they can be subjected to ILSA's cruel experiments, they formulate a plan of escape. The leaders are Anna and Rosette, two of the new girls, and Kala, who has been there from the beginning. Though she is dying a slow and terrible death as a result of having been infected with syphilis by the German doctors, she cannot pass up this opportunity for revenge. They are assisted by Mario, a veteran of many months in the camp and a castrated victim of ILSA's insatiable sexual desires, and by Wolf, a handsome young American who has just arrived.

ILSA catches Anna discussing the escape plans and has her taken to the underground torture chamber. Here she discovers that perhaps Anna is the girl she has been searching for. She is able to withstand unbelievable amounts of pain and ILSA in her excitement and sadistic frustration is forced to invent many bizarre and painful methods of torture to adequately test her. At the same time, she has taken Wolf as a lover. Because of his incredible sexual prowess, he alone is able to satisfy her. She rapidly falls in love with him. Wolf, seeing this as an opportunity to take over the camp and escape, welcomes her attentions.

The day of revolt is set. As ILSA lavishly entertains a high ranking member of the German High Command, who has come to the camp to present her with a decoration, the prisoners make their final preparations. They will attack when the General leaves, but as they wait, the General and ILSA retire to her rooms, where she satisfies his sexual perversions. Finally the General leaves and ILSA has Wolf brought to her as a way of cleansing herself after the degrading acts the General submits her to. By sexually exciting her with stories of what he is going to do to her and how much she will love it, Wolf manages to tie her to the bed. He then leaves and joins the others in their takeover of the camp. The battle rages but the prisoners are soon victorious. Wolf and Rosette beg the prisoners to make their escape, but they refuse, electing to stay with Kala and her plans for revenge. They alone set out for the surrounding mountains as Kala begins executing their ex-captors. Suddenly tanks appear rushing down the road to the camp. The inmates, thinking that they must be the allies rush to greet them. As the dust clouds settle and the vehicles smash through the gates, they realize that it is the Germans come back to destroy the camp before the allies can find it. They easily defeat the prisoners and set about destroying the camp. They find ILSA still tied to her bed . . . . .
