Hoby ends up shooting a 16-year-old boy in the back while tracking down a prowler. The townspeople think that Hoby acted wrongly, and the boy's father swears vengeance.

The Rangers send Hoby to a town to investigate the lynching of a half-breed. The townspeople claim that it was all a set-up to get the suspected killer to talk, and the horse bolted. But Hoby soon suspects that it was a second murder to cover the first.
