base on the average short story by horror writer stephen king about so called sleepwalker ancient and immortal cat like creature that suck the life out of virgin in order that this energy may sustain them they have supernatural ability they can make themselves wouldim which mean they become invisible and can create subliminal mirage to fool people . they have be flee human for century we be tell and have one by one be pick off till there be only two leave . the film start when a beautiful mother and her son arrive in a sleepy town and they be the last of the sleepwalker and they be on the prowl for virgin to fee on . the mother send her son out to enrol at the local high school so he can find a virgin and he do ( madchen amick ) and proceeds to try to get her alone so he can suck her dry . it be not make clear why the mother can not seek out virgin herself it would make thing easy one would imagine a teenage boy be much more apt to follow a old beautiful woman to a secluded area than a teen girl follow a teen boy . however his plan be thwart a the girl fight back and jab a pencil in to his ear . the police be call and the hunt be on . the son be sick from his injury and so the mother go on the rampage kill cop leave and right in her hunt for the girl who hurt her son and spout some painfully unfunny one liner amidst the gore . finally the girl kill the mother end of movie . this movie be rubbish . the acting be variable and from the average brian krause to the excellent alice krige . the special effect be average and and showcase some early computer effect which be mildly interesting a it show how far such thing have progress in such a short time . the direction be muddle and the film fall in to camp in place . the director seem unsure whether we be suppose to fear the sleepwalker or sympathise with them and when in doubt allow the film to become hysterical . stephen king make a mildly amusing cameo a an annoy gardener a do mark hamill and a a puzzled cop . alice krige seem to shoulder the film and her character be give depth and she give an indication of what the film could have be with a good screenplay and good direction .
