In Mexican California, a land feud erupts and murder is committed when rich landowner Don Domingo reneges on an earlier verbal promise made by his father to grant to the tenant Melo family a piece of land.

In old Spanish California, dashing cattleman Juan Obregon returns to the rancho of his friend Gaspar Melo, to find he's fathered a son on Rosa, one of Gaspar's identical twin daughters. Overjoyed, he plans to formalize his "unofficial" marriage. But trouble brews; Melo's land is of unclear title and the new Don Domingo hopes to grab it for his own profit. Violence results. Without even knowing who survived, Juan (accompanied by Rosa's tomboy sister Tonya) rides for revenge, through spectacular pastoral and wilderness scenery.—Rod Crawford <[email protected]>
