Rancho Deluxe (1975) on Netflix

Plot summary

Jack McKee turns his back on his wealthy family, and Cecil Colson, who is of Native American descent, seeks a path of his own away from his father. The two of them rustle cattle across Montana, cutting the animals up and settling bills with fresh meat rather than cash. Their main target is the herd of John Brown, a rancher who has bought up much of the land around with his wife, Cora, who is bored enough to try to catch the attention of Brown's ranch hands. Brown orders a helicopter search, with Burt and Curt aboard, to catch the thieves. When the rustling carries on, he calls on Henry Beige, a onetime cattle thief turned stock detective, who arrives with his niece, Laura, and seems to care only about television and being waited on.
