this film be basically a poor take on the old urban legend of the babysitter who get crank call tell her to check the child and she call the police who trace the call and find there come from inside the house . when a killer call have a story so simplistic a little kid could have write it . not much suspense and it become clear who the killer be halfway through the film . at the beginning and when the first victim be kill it look like a bondage fetish scene from a porn site or something . whats up with that . the film be oh so typical slasher fare with a plot about as original a a beatles concert . even by low budget slasher standard it cheesy . do not waste your time with this . nuff say .
