SYORU:
A couple, Harry and Buffy, are travelling across the Arizona desert in an ageing Bentley. Harry is English, a minor but arrogant and chauvinist movie star who regards his American wife as little more than a chattel. The car is misfiring and they pull in at a Navajo settlement for the night to rest and get the car fixed up. Next day, they carry on with their journey and, in the middle of nowhere, the car breaks down and they are stranded. Harry is determined to stick to the principle of staying by the car until someone comes. Night falls, and Buffy is convinced she sees a light in the distance. The stubborn Harry refuses to believe her, so she sets out alone to try to find it. Eventually she comes upon a shack in which live the Boy, a young widower, and his black dog. The Boy spends his time carving wooden dolls. His grandfather is the Navajo chief whose portrait we see hanging behind the performers. He had married a white woman. The "Dark Blood" of the title is the Boy's dark side....
