Ball's publicity man, Jack O'Riley (Gaxton), seizes upon the situation as a perfect PR stunt and convinces her to travel 3,000 miles to join Hooper at Winsocki Military Academy's dance. When Ball actually shows up, mayhem ensues. Hooper, who never dreamed she would accept, has to disinvite his girlfriend, Helen (Weidler), and ask Ball to pretend to be Helen, lest the actress herself not pass muster with the institution's screening committee.
Helen fights back while Hooper tries to keep Ball from the clutches of other cadets who want to steal her for their dates of their own. Meanwhile, Harry James and his orchestra perform various songs, including "The Flight of the Bumblebee". The cast also sing and dance their way through such numbers as "Buckle Down, Winsocki" (the tune co-opted in the 1960s for "Buckle Up for Safety"), "Three Men on a Date", "Alive and Kickin'", "The Barrelhouse, The Boogie-Woogie and the Blues", and "What Do You Think I Am?"
