seven year after a pledge be tragically kill in a sorority initiation rite and five of the other sister be invite to a remote mansion ( modern style and not gothic ) where they face a fight for their life and aid by two horny young men who be trap with them . why be they be kill and who be ( be ) the killer ( s ) . such be the premise of this fairly entertaining b horror or mystery movie . the acting be about par for this kind of movie and though it be clearly a product of the seventy and it doesn not seem too date . the story be a fairly straightforward and predictable one up until a very strange end that just doesn not make a lot of sense to me . however and there be some creative set ups to kill and and the film work fairly well even without gore or nudity and and little suspense . i think this be partly because the pacing be good and doesn not allow it to get too boring . not the great movie and but if you like b movie and then this one be surprisingly entertaining .
