Tonight's case from the files of the FBI concerns one of the most common crimes committed in the United States - auto theft. The file opens on a desolate road in a south western state, as a man and woman in a late model convertible make their way slowly through the night towards the Mexican border. Seeing a flashlight flicker a signal to them, they pull over. The man gives them the all clear to drive across the dry river bed, which will take them over the border into Mexico.
