There was a movie I saw a few years ago in which a family gets lost on a road trip and unspecified strange things begin the happen and the road keeps on going with no end in sight. The most notable part was when they turned on the radio and the only station available broadcasted the sound of several babies crying, and at the end, it turned out they were dead to begin with, or so I think. I keep thinking it had something in the title that referred to making a wrong turn, but it is not the movie "Wrong Turn."
