All the same stars of that other convulsive army comedy that was the most hilarious thing in khaki 'til this one came along!

Colonel Barkley is very proud of his assistant, Sergeant Doubleday, who has a photographic memory. Doubleday shows off his book knowledge on firearms during a class given by Sergeant Ames, embarrassing him. Through a series of misunderstandings, Colonel Barkley thinks the gun shy Doubleday is an expert marksman, and he sets him up in a shooting match against Ames and Sergeant Cobb.
