The Cellar (2006)

Hard-working Texas salesman Howard Rhodes is looking for a replacement. When he takes two potential candidates on the road - one, a womanizing musician, the other, a single mother - to determine who gets the job, Howard never considers the possibility that he might not return home. An unforeseen act of nature in a small Oklahoma town leave the three stranded in a cellar with nothing to do but find the truth about each other. And wait. And pray.
