After a cavalry man is killed at the beginning, there is some stock footage with sloppily credits that must have been added at the last minute narrated by Ray Danton that explains that there was a treaty and Yellow Shirt (Danton) is fighting all by himself his personal war. The movie simply consists of Yellow Shirt that stalks these Cavalry men and takes them down one by one.
In every single aspect, this movie is horrible. Apart from the narration, there is barely any talking in the movie. And they almost all mumble incomprehensibly throughout. And when it comes to the cinematography it's even worse. From time to time some scenes jump illogically. In particular when the movie focuses on the last surviving man, there is some footage of desert animals (a owl, a group of pecaris and a rattlesnake that is thrown away) that simply doesn't make sense whatsoever.
All in all, a truly sad and wretched movie only of interest to bad movie fans or if you want to see once-respected actors in career suicide mode.
