Valdez Is Coming (1971)
Western
Old Mexican-American sheriff Bob Valdez has always been a haven of sanity in a land of madmen when it came to defending law and order. But the weapon smuggler Frank Tanner is greedy and impulsive. When Tanner provokes a shooting that causes the death of an innocent man and Valdez asks him to financially compensate the widow, Tanner refuses to do so and severely humiliates Valdez, who will do justice and avenge his honor, no matter what it takes.
