Dixiana Caldwell and her friends, Peewee and Ginger, are circus performers in the antebellum South. When Dixiana falls in love with a young Southern aristocrat, Carl Van Horn, she leaves the circus where she is employed and, with Peewee and Ginger, accompanies Carl to his family's plantation in order to meet Van Horn's family. At first thrilled with the news of their impending nuptials, Carl's father and stepmother, Cornelius and Birdie Van Horn, throw a lavish party for the couple. However, Peewee and Ginger inadvertently disclose Dixiana's background as a circus performer, creating a scandal for the elder Van Horns.
Asked by the stepmother to leave in disgrace, Dixiana and her friends return to New Orleans, seeking to gain re-employment from her former employer at the Cayetano Circus Theatre, but they are regretfully refused by him, due to way she had departed. Desperate, she takes employment at a local gambling hall, run by Royal Montague, who also has personal designs on Dixiana. As part of his plan, he intends to financially ruin Carl and his family and use Dixiana to accomplish that purpose.
Things come to a head when Dixiana is crowned Queen of the Mardi Gras. When Montague absconds with her, Carl challenges him to a duel, but, when a disguised Dixiana shows up in his stead, she tricks Montague into revealing his nefarious plans. Carl and Dixiana are reunited.
