Nazi/bitch warden Helga (Malisa Longo) is in control of a prison during a fictional war in Europe. Women are brought in, then are beaten, humiliated and raped. Lots of sleaze and sadism. (Totally uncut). This is the English language version of Helga, La Louve De Stilberg (also available here at Rare Movie Collector).
NOTE: The picture quality for this film is a bit soft, but currently the best uncut English language version available anywhere.
