Hoping to increase its box-office allure by adopting the title of a popular song, Deep in the Heart of Texas (clap!clap!clap!clap!) was the first Johnny Mack Brown western of the 1942-43 season. The plot concerns a group of insurrectionists who intend to keep Texas separate from the rest of the USA.
