Our man is getting a little suspicious and finally rents a jeep from a young woman and goes out to Adobe Flats. There's an unmarked grave there, a burned-down house, and a functional well in the dry dry land. When he gets back to Black Rock, the primary evil guy lets him know he's going to be killed. He fights, one-handed, with another guy and wins.
He's asked why he's there, by friendly people, and tells them that a Japanese soldier fighting on our side saved his life in the war and died doing it. He was bringing the medal to the father. He finds out that the father was killed because he was Japanese and he had water, and then two people come to his side. They get him back in the jeep, the girl driving this time, and going to a city. They're ambushed and it turns out the girl was in on it. The sniper was her boyfriend, but he killed her anyway. Our man made a bottle rocket and threw it at him.
He took the sniper's car back, with the burned sniper and the body of the girl and Doc took the sniper to care for him. Soon, the train is coming again and our man is leaving. Doc talks him into leaving the medal, to make the town stay better.
