During World War II, a yodeling hillbilly singer goes undercover to expose a ring of Nazi spies operating in the United States.

Ozark thrush Judy Hull inadvertently shoots a pigeon carrying a message from a secret Nazi spy nest in the United States and becomes a national heroine. Philip Munson, head of the spy ring with headquarters in a secret room at the "Club 76", which he operates, receives orders from the Gestapo to liquidate her immediately as an object lesson to all Americans who might try to emulate her. When theatrical agents Cliff Little and Eddie McCabe come to Munson's office with Marie Lamont, a dancer they are trying to promote, Munson conceives a scheme whereby Judy will be brought to him, rather than him going to the Ozarks to liquidate her. He tells Little and McCabe that if they will produce the now-famous Judy Hull as an entertainer at his club, he might be interested in making a deal to employ their client.—Les Adams <[email protected]>
