Beneath the Dark (2010)
From IMDb:
Paul and Adrienne, a young couple burning up the desolate miles on the road between Texas and LA, check into the equally desolate but eternally stylish Roy's Motel and Café.
As if preserved in time, the motel proves to be a strange and surreal place where the guests are forced to confront the secrets that they keep – from the world and from each other.
