Saw this movie on Netflix sometime in 2013, it was set in a desert in the U.S. a couple became stranded and met a man down the road who really seemed to know his way around. They wind up getting to a ghost town where an old religious broadcast repeats on a loudspeaker. After awhile he tries killing them, they find their son dead in the trunk of their stranded car. At the end of the movie either the husband or wife, or both, find hundreds of thousands of crosses covering graves made by this guy.

Please help me, I’ve recently renewed my Netflix and would love to watch this again.
