Curley Smith, a lieutenant of the Texas Rangers, gets chased by a band of smugglers after getting caught spying on them and becomes injured. Anita, the daughter of the chief smuggler tends to him and the two of them fall in love. Dean, a member of the renegade, becomes jealous of their romance, and will do whatever he can to get rid of Curley - fair or foul.

The first, and apparently only, surviving film produced by the Colorado Motion Picture Company, Pirates of the Plains is a quite well-made story about two brothers, one a champion rodeo rider, the other a horse thief.
