three girl ( an all female medium crew and include cult actress barbara bach and no less ) visit a small town to cover a festival and end up rent room in a house they should have avoid like the plague . well make little shocker and suffer a bit from some redundant dialogue scene and a rather thin plot line ( that doesn not do very well in hide it secret ) . one underlying theme in particular be quite disturbing ( a in represent vintage shock material ) and and this be basically what the film thrives on . performance and cinematography be pretty much above par ( compare to many other late 70 or early 80 film in the same vein ) and but what really make me recommend this film be the fairly long climax scene in the basement set . from the moment that keller junior character be introduce and his performance make my jaw drop open and it do not close until the end of the film . a very pleasant surprise to see actor sydney lassick ( who be funnily wacko in one flew over the cuckoo nest and and now utterly demented in the unseen ) take on one of the lead role .
