Help me out

Hey there, I'm searching for a movie I saw some time ago and want to re-watch it but can't recall the title.
I remember at the beginning of the film a few teenagers/younger adults riding down a (lonely) road in the car and one girl of them looking through the window of the car, seeing a man at the forest edge throwing a corpse packed in some garbage bags in a hole. I remember the movie itself being bad-ass but can rememer anything else from the story, maybe it rings a bell for one of you guys.

Every generic horror-flick ever made?

Well I'm sorry I can't get more into details on this one haha
I 'guess' the people in the car get chased from this mysterious dark man who threw his trash in the forest afterwards and the whole film starts a bit mysterious too. Oh and I just remember that the woman who looked at the mysterious dark man got seen from the mysterious man watching him throwing his mysterious trash there, and she was like 'oh fuck he saw me' so they drove fast away. After that I have a black-out
Pretty mysterious
