Wild Horse Rustlers

Tom Cameron, known as The Lone Rider, and his partner, Fuzzy Q. Jones, are cautioned to keep an eye out for Nazi saboteurs while they fulfill their commission to buy horses from the Flying Horse Ranch in Texas for the U.S. Cavalry. When they arrive at the ranch, they are greeted by Ellen Walden, the owner's daughter. Tom and Fuzzy's arrival is fortuitous as they are able to save foreman Smoky Moore from being shot by ranch hand Bruce Collins. Collins later reports his failure to his real boss, Hans Beckmann, Smoky's long-lost twin brother, who grew up in Germany and is now a Nazi spy. Beckmann is on a mission to destroy every horse intended for the cavalry, and he plans to kill Smoky and impersonate him. When Collins, who was a reluctant follower of Beckmann, tries to quit, Beckmann kills him. Tom and Fuzzy hear the gunfire but arrive too late. Fuzzy retrieves a German-made jacket from a campfire near Collins' body, and they are then shot at by Beckmann and his gang. When the sheriff arrives with a posse, Beckmann, posing as Smoky, turns Tom over to the sheriff as Collins' murderer. Both Tom and Fuzzy are put in jail, while Beckmann takes Smoky hostage, and introduces his cohorts to Ellen as new ranch hands. Fuzzy discovers that the jacket he saved belongs to a Nazi, and Tom, confused that Smoky would turn them in, suspects that he is involved with the Nazis. Tom and Fuzzy trick their guard and escape from jail, and then break into the mortuary and exhume Collins' body. Tom then douses the lights at the Flying Horse bunkhouse and makes Beckmann believe that Collins is speaking to him through a window. From their conversation, and Fuzzy's remembrance of Smoky's German twin, Tom determines that the man posing as Smoky is an impostor and a Nazi spy, and suspects that the horses are their real target. The next day, Fuzzy and Tom intercept a wagonload of poisoned hay intended for their horses. Tom burns the hay, and the next day, identifies himself and Fuzzy to Ellen and Beckmann, who is still posing as Smoky, as the government purchasing agent. Later, however, Tom tells Beckmann that he is a rustler, and learns of Beckmann's plan to kill the horses. Beckmann sends his cohort, Jake to work with Tom and Fuzzy, but Tom forces Jake to take him to the hideout where they are keeping Smoky. After knocking Jake out in a fistfight, Tom releases Smoky and they head back to the ranch. Fuzzy, meanwhile, leads the sheriff and his posse to the ranch, where they accuse Beckmann of being a Nazi saboteur. Beckmann at first tries to confuse the sheriff, but when Smoky shouts "Heil, Hitler!" the Nazis instinctively salute. Beckmann attempts to escape, but is caught by Tom and arrested. The horses are then rounded up for the cavalry.
