Hey Kindertrauma!
I need some help finding a crummy slasher movie.
I saw it on TV in the late '80s or early '90s, probably on USA Saturday Nightmares or Commander USA's Groovy Movies.
The only bit that really stuck with me was a stalking chase sequence along a row of bushes or hedges. I think the victim (not sure if it's a boy or a girl) was hiding up against the bush when the killer stabs them with a long pole all the way through both the bush and the victim's body. Then there's a nice closeup of blood dripping out of the pipe – that's the part I REALLY remember.
Sorry I don't have any more to work with. And Thanks!
