This Spanish western from 1969 takes place in the northern section of Mexico. When a Texan comes to town and saves Erick (a young peasant about to be hanged by a group of local scoundrels), the two form a partnership and seek revenge on the men in question. The fighting only escalates when Erick and his Texan partner take a job working for the daughter of a man who was killed by the same crooks, culminating in a fierce duel to the death.
