Beau Clemment II, 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, Thadeus Jackson, in a game of chance. Thadeus 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. Beau travels to
Alabama to claim the boat, which he finds in something far less than ship-shape condition. Unsure whether to scrap it or sell what's left of it, Beau meets singer Sally Jane Jackson, granddaughter of Thadeus, and they develop a mutual attraction. He elects to restore the vessel and launch it with entertainment and gambling. He even recruits Thadeus's singing butler, William, to perform aboard ship. Thadeus objects to Beau's ownership and presence, doing everything in his power to scuttle the venture. By the time the law catches up to it, Beau's boat has sailed into
Georgia, out of its jurisdiction. Thadeus, 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. ==Cast==
