With one of the best titles in Christendom this cult classic centres around a group of high school students who plan a slumber party while their parents are away for the night. Enter a random psycho-killer, on the loose from a mental asylum and armed with an assortment of power tools (all conveniently cordless). There are a couple of good, hearty deaths, but while it's not the worst this sub-genre has to offer it's also nowhere near the calibre of some other suburban fright-flicks, like 'Halloween'.
