Two families in a small town, the Canovas and the Mayfields are perpetually feuding. Each family prides themselves on their military tradition, with the Canovas having a statue of an ancestor who fought in the American Civil War holding a pride of place in the town with the Mayfields trying to replace it with one of their own Mayfield ancestors.
A Romeo and Juliet situation develops where Judy Canova is in love with Lieutenant Tom Mayfield of the Army Ordnance Corps, but Tom pays more attention to the glamorous Doris Vail. Vail tricks Judy into joining the Women's Army Corps to get rid of her. The joke is on Doris when Tom is enthralled with Judy's patriotism and accompanies her on the town hayride. When Doris finds out Judy will be sent to basic training at the same army post Tom is at, Doris enlists herself.
Following basic training, the pair get assigned to Tom's Ordnance unit that is testing a secret missile guidance device that attracts the attention of an enemy spy ring.
