Synopsis: When meek music conservatory headmistress Katharine Hillard first meets Barry Clayton, the arrogant swing bandleader doesn't think much of the bespectacled teacher. Despite his off-putting attitude, Katharine falls in love -- not with Clayton but with the vibrant new brand of music he plays. She decides to pursue her new passion whatever the cost. After an impressive makeover, she attracts not only Clayton but also swooning singer Jimmy Hale.
