Comparison between the R-Rated and the Unrated version.
Trashy but very entertaining party-splatter which is a mixture between a women's prison movie and a zombie flick. The part of Shadow is played by none other than Tony "Candyman" Todd. The other actors and actresses are relatively unknown but still do a pretty good job.
In the USA both an R-rated and an uncut Unrated version can be purchased on DVD. But against the common trend, it is not mostly story extensions that lead to the version being Unrated but it is actually mostly cuts of splatter scenes. So look out for the rating when buying the movie!

Unrated version = 91:27 min.
