Ace pilot Tailspin Tommy has invented a groundbreaking new bomb targeting system that will revolutionize the Air Force. On the eve of the system's delivery, a treasonous group of spies kidnaps Tommy to force the plans out of him. When the villains threaten Tommy's girlfriend, the pilot is forced to choose between his country and his love. Unable to turn his back on either, Tailspin Tommy risks everything on a heart-stopping plan.
The first of four Monogram films based on Hal Forrest's comic strip, "Tailspin Tommy," Mystery Plane was a showcase for some talented people who went on to greater acclaim. Director George Waggner directed The Wolf Man (1941) and Marjorie Reynolds appeared opposite Boris Karloff in Monogram's Mr. Wong series and starred in Holiday Inn and Fritz Lang's Ministry of Fear.
