This slightly odd thriller is another of the early 70's movies which played upon the fears generated by the Manson Family murders of 1969. These 'counter-culture gone bad' movies often focus on cult groups who commit crimes and this movie is no different in this regard. Set in Amsterdam, a detective investigates a series of vicious house invasions committed by a gang of rich youths. They don't need money, so the source of their crimes turns out to be cult based.
Opening with a disturbing attack on a married couple where the woman is gang raped while the husband is forced to helplessly look on, this is a movie which doesn't pull its punches. Its sexual frankness is at least partially down to its Dutch origins I am guessing, seeing as this nation was, and remains, one of the most sexually liberated in the world. This results in a film with a great deal of matter-of-fact full-frontal nudity throughout but also the graphic opening attack sequence. So the film definitely falls into the exploitation bracket, although it isn't all that excessive beyond this particular scene. It soon afterwards boils down to a detective story running parallel to one detailing the dramas surrounding the criminal youths. It's not in all honesty all that dynamically told to tell you the truth and it is a little uneventful overall. I thought also that the whole cult side of the story could have been magnified more, as this type of thing never really gets old but it was underplayed here somewhat. Still, this is still a reasonably distinctive film, probably mainly on account of it being a counter-culture themed film from the Netherlands, which is not exactly the norm. Definitely worth a watch but it's nothing too essential.
