Back in the '80s on Argentinean TV I saw a horror American movie (I was quite young at that time) and I could never find out its title (in Spanish it was something like "Horror is written in blood",but translations in here are quite inaccurate and often misleading...I only remember a scene in which a teenager,after leaving his girlfriend and her kid brother at her place, arrives home and something pulls him under the bed , next thing we see is blood oozing from there ...I know it's just a tiny bit of info but if some of you 80´s horror fans can help me locate this movie, I'd be extremely grateful...
