On a lonely Arizona back road, two traveling salesmen are stranded when their car breaks down. Stuck there through the night, they take time to reflect on their jobs and the beauty of the sandstone all around them as they fall asleep. However, they awake in the middle of the night to find the desert populated with the swimming ghosts of sea life long past. When the younger salesman manages to join in the beauty by jumping up into the parade of animals, his euphoria is short-lived, when the ghost of a giant shark consumes him.
