Roy Rogers (as Roy), Smiley Burnette (as Frog), and the "Sons of the Pioneers" go undercover to help Texas Governor Russell Hicks stop World War II Axis sympathizers from blowing up U.S. warehouses. Not a war story, but a Roy Rogers western: this one a "Variety Show" of stunts, songs, and Smiley bits
plus, a sign proclaiming: "Freedom of Speech Doesn't Mean Careless Talk".
"King of the Cowboys" songs include: "I'm an Old Cow Hand", "The Gay Ranchero", "Prairie Moon", and others. Stunts include setting up a giant mirror on a road to simulate a head-on car crash; and, following another car crash, Rogers being tied up and left in a warehouse rigged to blow. The story is inconsequential. Following the stunted end, Rogers is introduced as "King of the Cowboys" and sings "Ride Ranger Ride". Formulaic to the hilt!
