Good old Trevor Barley (hiding behind an alias, Roman Nowicki). Clearly spotting a gap in the market, he made this, an erotic horror about a serial killer murdering young women. Even though it was all made in the UK, fearing the authorities, Barley set it in Poland and hired Polish/Russian actresses who speak in their native tongue in the film, thus it's dubbed and looks like it comes from Poland. Clever!
Anyway, the film itself is pretty unremarkable and technically inept - the killings are mysogny to a whole new level with buxom babes being stripped completely before being killed in cruel and unusual ways (one is raped by a knife!).
How anyone can compare this to the works of Fulci or other great Italian directors is beyond me - this is a very cheap and nasty film that is only passable as entertainment and just not that shocking. The ideas certainly are, by the way its made dilutes it so much that you end just watching the screen for the sake of it.
Best to borrow a friend's copy first and see what you think - you may enjoy it, but you may not. I for one, didn't really; it was viewable but could have been so much more with a little more time, effort and money.
