Advertising man, J. Roy Thomas, is stymied in his
attempt to sign an act for his
biggest client, Kornies Breakfast Food. Every time Thomas signs an act for the
breakfast food's radio show, his deluded client, McKenzie, who fancies himself a
musical talent, insists on joining the band and otherwise ruining the broadcast.
Unable to find any local talent willing to put up with his client, Thomas sends
his aide, Patricia Reynolds, played by an effervescent Anne Gwynne, to Yubaville, Iowa to sign the group Gabe Morgan's
Rhythmeers.
While his band mates jump at the chance to move to New York City,
Gabe is reluctant to take his orphaned niece, Baby Sandy, away from the quiet
life of Yubaville. Pat uses her feminine wiles to woo both Gabe and Sandy, and
the group finally agrees to the move.
The female Rhythmeer, Mary Lou, however,
soon becomes jealous of Pat's intense interest in Gabe. Once they arrive in New
York, Gabe and the band suffer the same fate as their predecessors, as McKenzie
again insists on joining the act. After a particularly crazed rehearsal, Gabe
threatens to quit the group and move back to Yubaville with his niece.
He is
especially incensed because he suspects that Pat is romantically involved with
Thomas, and that she "played him for a sucker" as she collected a $5,000 bonus
for signing the band. The rest of the Rhythmeers are keen to stay, however, and
Mary Lou is particularly determined, as she is the one who is actually involved
with Thomas.
In the meantime, child performers Butch and Buddy, who have been
seeking an audition with Thomas, finally corner McKenzie with their new act,
which includes Sandy playing the xylophone, something she usually does with her
uncle's group.
After a madcap audition, the two boys rush away, leaving the
young girl behind. Sandy's apparent disappearance causes a sensation and leads
to a frantic search. When McKenzie attempts to take the young girl back to
Thomas' office, he is immediately arrested by the police for kidnapping.
The
sponsor is taken to police headquarters, where he is met by Pat, Gabe, Thomas
and Mary Lou. Pat then hatches a plan to blackmail McKenzie into agreeing to
refrain from interfering with the Rhythmeers if they clear him of the kidnapping
charges. McKenzie reluctantly agrees, just in time for the show's initial
broadcast. As the show is about to begin, Thomas and Mary Lou announce their
engagement, as do Gabe and Pat.
