On a USO tour during World War II, entertainer Eddie Sparks needs a partner to round out his act. Soon after hiring performer Dixie Leonard, Eddie decides he wants her out of the show — mostly because she upstages him.

As the years and wars go by, Eddie and Dixie experience a tumultuous relationship onstage and off while they continue the act for the troops.
