Beloved actress Lucille Ball plays herself in this lively musical comedy, based on the Broadway play and featuring the music of popular bandleader Harry James. When young military cadet Bud Hooper (Tommy Dix) invites Ball to be his date at the academy’s prom, her agent convinces her that accepting would be a great publicity stunt. Soon Ball’s presence at the school leads to chaos, and the redheaded celebrity unwittingly incurs the wrath of Bud’s girlfriend, Helen (Virginia Weidler).
