Where the Shadows Fall

We have a guy with a jeep being pulled by a couple horses. He is looking for his wife and child. He is obviously a mess and completely deranged. He is willing to shoot people in cold blood. He goes to get some water at one point. A guy shoots at him and he kills the man. Later, when he comes upon a caravan of people in theatrical garb (and running a prostitution ring), he fixates on one of the women, What happens next is just so strange. But we are being led by a man with a truly sick mind. The problem is the film and the storytelling.
