A young couple's car breaks down on a desolate road in the desert. While waiting for a tow truck the woman falls asleep only to discover later that her boyfriend is missing and the tow truck has never arrived. Talking on the phone to an acquaintance about her situation she slowly comes to the horrifying realization that the strange person on the other end of the line knows more about the situation than does she. ~ Erin Demers, Rovi
