The story is about a New York nightclub singer who inherits an old riverboat on the Chattahoochee River between Georgia and Alabama.

Beau Clemment, a singer in New York City, learns that he has inherited a riverboat once owned by his grandfather, Beauregard, who had won it from its captain, Thaddeus Jackson, in a game of chance.

Jackson has been bitter ever since, his old acquaintance Humphrey Hepburn recalling how Beauregard also won the heart of the vessel's star performer, Melissa Curry.

Unsure whether to scrap it or sell what's left of it, Beau meets singer Sally Jane Jackson, granddaughter of Thaddeus, and they develop a mutual attraction.

Thaddeus, finally accepting the situation, is given a 50-50 interest in the boat with Beau, who is about to wed Sally Jane and become a part of the family.
