Banditos Jim Hawkins (MacMurray) and Wahoo Jones (Oakie) roam the Texas frontier until the Rangers come in, establishing order. So, they switch over to the good guys but are then told to bring in their old partner-in-crime Sam McGee (Nolan). Lots of confronting villains and battling varmints. Based on the book by Walter Prescott Webb. Followed by "The Texas Rangers Ride Again" and remade as "The Streets of Laredo" (1949).
