An outlaw boss they call "Nevada", a.k.a. Mr. Perdue, has not only been hitting on Johnny's girl Margaret, but also rustling her father's cattle. Cassidy receives a message to help, but before him and Red can leave, the hotheaded Johnny heads alone out to win Margaret back. Hoppy poses as a gambler to infiltrate the outlaws and runs into a grizzled old windbag that he nicknames Windy. The four of them team up to battle the outlaws in an exciting climax. Another fine Hopalong Cassidy film, and an important one since it introduces George (Gabby) Hayes as Windy.
