Bandleader Kay Kyser takes his troupe of nutty musicians, goofball comics and pretty girl singers on a tour around the world to entertain the troops during World War II.
Justo antes de embarcarse en su luna de miel, el soldado Kay Kyser recibe la orden de presentarse en el cuartel general para una peligrosa misión: actuar como espía en un club nocturno donde parece ser se ha localizado a un grupo de nazis. Su esposa Terry no parece conformarse con la soledad, así que parte en busca de su nuevo marido. Esto, unido a la torpeza de Kyser y la intervención de una rubia agente secreta dará lugar a todo tipo de situaciones cómicas.
El representante de la banda de Kay Kyser les consigue un contrato para actuar en la fiesta de cumpleaños de una rica heredera, en una mansión aterradora, donde fuerzas siniestras intentan matarla.
J. D. Forbes, head of the almost-bankrupt Four Star Studios in Hollywood contacts band leader Kay Kyser, who puts on a radio and-live theatre program called "The Kollege of Musical Knowledge," to appear in films. When manager Chuck Deems gets the studio offer, he and band members Ginny Simms, Sully Mason, Ish Kabiddle, Harry Babbitt and the others are all fired up at the prospect of going to Hollywood and working in the movies, but band-leader Kay is all against it and says his old grandmother has told him to stay in his own back yard, but he relents. Once there, Stacey Delmore, a Four Star associate producer left in charge of the studio while Forbes is out of town, discovers that the screenplay writers have prepared a script that has Kay Kyser playing a glamorous lover in an exotic European setting.
