San Miguel is a one horse town that's being pulled apart by two rival families. John Baxter, the crooked town sheriff with a sideline in weapons smuggling, seeks to establish his own version of law and order with support from his son, Antonio and their gang of thugs. But the Rojo Cartel - headed up by a trio of volatile brothers: Miguel, Ramon and Esteban - have their own ambitions for San Miguel and its strategic position on the Mexican border.
Enter the Man with No Name: a laconic gunslinger for hire who drifts into town and, after learning of of the Baxter-Rojo feud, spots an opportunity. He plays the warring clans off against one another and turns their vendetta to his advantage - but the stranger's duplicity riles both families, and the vengeful Rojos decide to take drastic action in the battle for San Miguel.
