When Delaney Mossbacher knocks down a Mexican pedestrian, he neither reports the accident nor takes his victim to hospital. Instead the man accepts $20 and limps back to poverty and his pregnant seventeen- year-old wife, leaving Delaney to cruise back to his privileged life in California. But these two men are fated to oppose each other, as Delaney attempts to clear the land of these illegal immigrants he thinks are turning his state park into a ghetto, and a boiling pot of racism and prejudice threatens to spill over.
