RKO Radio's second 3D production, Devil's Canyon is a combination western and jail-break picture. The scene is Arizona Territorial Prison, wherein 500 desperate men are incarcerated. The inmates become even more desperate when female outlaw Abby Nixon (Virginia Mayo) is likewise locked up. As the prisoners draw up plans to escape, Abby is attracted to handsome but psychotic ringleader Jessie Gorman (Stephen McNally)--and to U.S. marshal Billy Reynolds (Dale Robertson), who is serving time for manslaughter. The climactic bust-out threatens to get out of hand until the marshal calms things down with a Gatling gun. Available for many years only in washed-out black-and-white prints, the original color version of Devil's Canyon was finally telecast over the American Movie Classics cable service in the late 1980s. ~ Hal Erickson, Rovi
