Can anyone help me?
 

There's this horror movie I watched in Croatia, it was in like Spanish or something like that,
but with English subtitles, anyway, it's about this serial killer guy who looks like some farmer dude,
and he kills this womans family, and yeah, hard to explain, but it was a veeery weird movie,
it also had a weird title.. it was something really weird and hard to remember haha.
I'm hoping someone could help me here. :D

haute tension/high tension/switchblade romance?

Sounds alot like high tension.
