A mother and father set out with their two children, driving from New York to Arizona in the heat of summer. Their destination: Apacheria, the place the Apaches once called home. Why Apaches? asks the 10-year-old son. Because they were the last of something, answers his father. In their car, they play games and sing along to music. But on the radio, there is news about an "immigration crisis": thousands of kids trying to cross the southwestern border into the United States, but getting detained --- or lost in the desert along the way. As the family drives, we sense they are on the brink of a crisis of their own. A fissure is growing between the parents, one the children can almost feel beneath their feet.
