One of those films where title tells you pretty much all you need to know about the plot. A group of girls head over to their school friend Trish's (Michelle Michaels) house for a sleepover, as her parents are away for the weekend.
But unfortunately for them, there's an escaped convict on the loose who's going round murdering people with an industrial power drill. Having already murdered a hapless telephone repair man and taken his van, he then sees about crashing their party and carving people up with his drill in loving detail.
As the bodies pile up, it seems no one in the neighbourhood is safe. As the neighbour, the girls boyfriends and even the pizza delivery guy all fall prey to the maniacal driller killer, as the girls attempt to arm themselves and fight back.
Produced by the infamous B-movie producer Roger Corman, "Slumber Party Massacre" was one of many 80s horrors filmed to cash in on the success of "Friday the 13th", and features plenty of blood, guts and (best of all) female nudity, which no decent 80s slasher movie should be without. So its kind of hard to imagine that this actually had a female director and was written by a noted feminist author (no, seriously).
Whilst perhaps not as memorable as other period movies of its ilk, this is never the less a highly entertaining low budget romp, which actually went on to spawn a number of sequels and spin offs. If you haven't seen this one yet, you should definitely check this one out.
