Sergeant Gene Autry, Smiley Burnette, and the Ranch Boys have served out their enlistment, but Gene convinces them to re-up by singing "My Buddy." Before he can sign his reenlistment papers, Autry is sent by Major Robert Warwick to talk to a ranch town near the camp; the army needs the land for a practice range, but they don't want to give up their land. Autry goes in as having bought one of the ranches, and Burnette and the boys desert to go with him. He just about convinces them, but there's someone using a biplane with Army markings to wreak havoc, which gets everyone's freedom-loving blood up.
There are plenty of loose threads left hanging in this singing western, but if you want to see a US Cavalry charge in 1939, Burnette destroying everything in sight as he instantly figures out how to maneuver a tank, and hear favorites like "Tumbling Tumbleweeds" and "Born In The Saddle", this is the mildly incoherent but very patriotic movie for you. With June Storey, Gabby Hayes, and Jonathan Hale.
