I watched this movie when I was college so it was around 2012~2016 but couldn't find it when I was searching on Google. It was a random movie my roommate downloaded from internet and I played it when I was bored.

I think the movie was not English, foreign made movie and foreign language and I think I watched it in subtitles. Plot of the movie - Man and Woman are hiking around and making out and stuff in hills or mountains and I think the Man steps on IED bomb and then later they see sign of danger of bomb mine ahead or something. So a local man comes and sort of rape the girl, he tell the man if he moves the bomb will explode cause it is pressure bomb or something so the man can't move and save his girlfriend from being rape and the local man rapes his girlfriend in-front of him (like there a lot of torture in between like she tries to run but can't find signal on her phone or something, local man beats her or something like that and the movie drags like 1.5 hours about just local man torturing and trying to rape the woman).

Major spoilers below, this happens when quarter of movie is left

The local man than later tells the boyfriend, you Americans are stupid, IED/Pressure Bomb don't work like that, your american movies make you believe in all this and fear of bomb exploding.

And I am not sure what happens next, I think my memory has confused and I thinking of another movie but I think the girlfriend dies and the American boyfriend find that local man, That local man is a family man with wife and daughter. American boyfriend sort of runs around in local mans home trying to kill the local man, and then finally grabs local mans wife and daughter and rapes them in-front of the local man and the local man can't do anything and the movie ends.
