This action-filled western has Gene playing a postal inspector investigating a gang empire headed by the nefarious Big Jim Lassiter (veteran character actor, Thurston Hall) who help finance their operations by robbing the mail stage. Gene poses as a robber known as the Whirlwind because he moves surreptitiously across the prairie like a dust devil. Gene hooks up with a fellow undercover postal inspector who turns out to be Smiley Burnette. It's a treat for fans to see the two together in the twilight years of the Saturday matinée cowboys. The romantic duties are performed this time around by the captivating lady from Arkansas and TV's Annie Oakley, Gail Davis, playing Elaine Lassiter, niece of Big Jim, who took her in following the mysterious death of her father, Big Jim's brother. In the process of getting the goods on Big Jim, Gene and Smiley tangle with some of the toughest of the budget western badmen including the likes of the unflappable Dick Curtis who was also adept at slapstick comedy. Playing henchman Lon Kramer, Dick and Smiley have a grand old time, especially in their first encounter where Smiley whips Lon and his buddies in a fisticuffs filled with belly laughs. Harry Harvey as the crooked sheriff, Harry Lauter as a shyster attorney, and a bevy of bad guys, including Bud Osborne and Kenne Duncan, make for a delightful outing. Stan Jones, who wrote the title song, has a bit part. A talented singer/songwriter and member of the classic Sons of the Pioneers, Stan is today best remembered for penning the oft-recorded "Ghost Riders in the Sky." Also in the music department, Gene and Smiley harmonize beautifully on the novelty ditty "Twiddle O'Twill," co-written by Gene with help from Fred Rose who is credited with discovering Hank Williams Sr.
A note of interest, Gene shows off his skill as a telegrapher, a job he was doing in Oklahoma when discovered by Will Rogers.
