Synopsis: The Civil War may be winding down in the Union's favor, but a band of marauding Confederate soldiers led by Wade McQuarrie is still hell-bent on crippling the North any way possible. Union soldier Gene Autry and his buddy "Cougar" are likewise determined to end McQuarrie's reign of terror against the divided nation. The two patriots ride out to Utah to prevent the rebellious Southerners from destroying the Army's supply lines.
