Plot
Following World War II in 1945, at a U.S. Army hospital unit in France, Pvt. Hogan does not believe that a blue-stocking can ever be good-looking. Catching first sight of new arrival nurse Lt. Betty Bixby convinces him otherwise. He picks up her dropped cigarette lighter after putting aside his M-1 rifle. He is seen by security officer Capt. Paul Lock, who admonishes him for doing so while Hogan is standing night guard duty. Lock confines him to quarters preliminary to a court martial. The colonel in charge of the hospital, however, would prefer to keep everything "in the family" and avoid a court martial. He knows it would be bad for camp morale and discipline, their unit being close to being sent back to the U.S. for discharge from the service.
Hogan begins to organize a ball at an off-limits hotel before their unit disbands. This will be to benefit all the camp's nurse officers and his fellow enlisted soldiers (men being men and women being women), in spite of army regulations. Private Hogan temporarily appropriates one of x-ray officer (radiologist) Staff Sergeant Perkins' fluoroscopic images, one with an image of a duodenal ulcer. He brings it to Lieutenant Betty Bixby's attention, unofficially; asking her to treat it surreptitiously, instead of ordering him to sick call, whom he wants to take to the ball. Lieutenant Bixby orders Private Hogan to report to her every two hours, to drink a cup of milk and cream (half and half), to prevent a perforated ulcer. Later, she discovers how Private Hogan falsified having an ulcer, then loses faith in him.
Hogan and Cpl. Bohun go through all sorts of mishaps to make sure that the plan for the secret ball goes ahead. It snowballs into constant wheeling-and-dealing and complex maneuvering by Hogan and soon others of his fellow camp soldiers. As the various details surrounding the ball grow larger and ever more complex, their efforts evolve into a "Mad Ball" that no one will likely ever forget ... if Hogan and his men can carry it off.
