Chaco is a young Mexican who finds himself blamed for the killing of two cattlemen.

A group of Americans has already tried to hang him, and he escapes and makes for Mexico. The bounty hunter Roger follows, set on collecting the reward, and Chaco's fiancee Asuncion is after him too, driven by jealousy. The men who did the killing are still at large. In San Rosario the locals greet him as a hero and take his side.
