A young woman (Tania Busselier) has herself committed in order to locate her captive sister, but quickly realizes she has entered a hell of sexploitation from which she cannot escape. Dyanne Thorne plays Ilsa to camp excess but it is the ingenue, Lina Romay (Female Vampire), who steals the show as Ilsa’s pet prisoner, a woman who withstands Ilsa’s abuse and manipulates her fellow prisoners, doing anything to stay alive long enough to turn the tables on cinema’s most diabolical villainess.
