The Flying U Ranch.

Migual Garcia, a somewhat arrogant Spaniard, alienates pretty much all of the residents of the Flying U Ranch except the owner's young son, Chip Bennett. Dunk Whitaker, who owns a neighboring ranch, has secretly been rustling Flying U cattle and steals a contract guaranteeing the Flying U's rights to a particular waterhole. Not only that, he decides that he wants Bennett's pretty niece, Sally, for himself. Just when things look their darkest, it turns out that Miguel is not quite what he seems to be.
