The title character in this standard comedy about the foibles of military life is Archie Hall (Robert Mitchum), a puffed-up dandy whose strutting personality makes the other privates in a Civilian Pilot Training program absolutely certain he is a spy. They figure him for a multiple-star general, out to entrap a Japanese spy by the unlikely name of Cindy (France Nuyen). A series of enlisted men and officers contribute to the misadventures due to the misunderstanding, including comics like Don Knotts as Captain Little and Louis Nye as Private Sam Beecham. Jack Webb directs, and plays the role of Archie's sidekick.
