A man who has just embezzled money from his company is driving through the Nevada desert. He picks up a pretty girl and her seemingly goofy boyfriend. The girl is a Las Vegas showgirl and the boyfriend turns out to be a professional killer, and he has no intention of letting the motorist finish the trip.
