Singing idol Conrad Birdie (Jesse Pearson) is drafted, sending the teenage girls of America into unashamed panic. The effect is almost the same on songwriter Albert Peterson (Dick Van Dyke) who had written the title song for Birdie's next movie. Kim McAfee (Ann-Margret) from Sweet Apple, Ohio is the girl chosen to receive Birdie's last civilian kiss. But when Birdie and his entourage descend on Sweet Apple the laughter really begins and never lets up.
