Help remembering a horror movie - eviltoast

About 4 years ago, I watched a movie which I enjoyed but can’t for the life of me find. It involved a white couple getting lost in deep rural Appalachia and getting taken in by a cult-like small family in the middle of nowhere.

I don’t remember the details very well since it was a few years ago and I watched it pretty late at night. I think it involved the woman being drawn in while the man wasn’t, and there being murder (in a shed?), but that could be me mixing different movies up.

Does anyone know what it might have been?
