An Anglo land speculator in California (Brodie) has the owner of a large land grant with roots dating back to Spanish colonialism murdered, but doesn't count on his son (Jason) showing up to defend his murdered father's claim. By this time Brodie has already divided up the land and sold it to unsuspecting Anglo settlers. Jason's arrival is pretty well done, as the first Anglo trespasser/settler he meets fights him with a pair of brass knuckles and Jason detaches one of the spurs off of his boots and slashes the guy's face with it. There are some other out-of-the-ordinary scenes in this film that make it moderately fun to watch, though the film for some reason cloaks Jason's character as a Spaniard, when he's really Mexican, and all of the land was Mexico until the treaty ended the war that enabled the US to confiscate it. But whatever, Brian Keith's hired gun character is pretty decent, and Jason's rescue of Mala Powers in the desert is not bad at all. Same with Brodie, who nails the part of the scheming real estate broker.
