Republic had lost Gene Autry to the war effort and this film, more than any other, brought the heretofore also-ran singing cowboy to the forefront, where he remained through the early 1950s. Following the example of Autry, Roy played himself, a rodeo star assigned by the governor (Russell Hicks to investigate a series of warehouse bombings. With sidekick Frog Millhouse (Smiley Burnette) in tow, Roy infiltrates the Merry Makers, a touring tent show whose phony mind reader, Maurice (Gerald Mohr), is the chief operative for a sabotage ring run by the governor's secretary, Kraly (Lloyd Corrigan). But Maurice catches Roy stealing his book of codes and is about to shoot him in cold blood when tent show owner Dave Mason (James Bush) interferes. Maurice then eliminates Mason and frames Roy for the killing but despite this setback, Roy manages to stop the saboteurs before they can blow up a supply train needed in the war effort. An "everything but the kitchen sink" action thriller, King of the Cowboys came complete with seven songs performer by Rogers, Burnette and the Sons of the Pioneers, including "Ride, Ranger, Ride", "Roll Along Prairie Moon" and Johnny Mercer's "I'm an Old Cowhand". The film was restored to its full theatrical length by the Roan Group in the late 1990s and re-released on a DVD that also features the original theatrical trailer and alternate scenes from a separate version released only to the military.
