In the vibrant setting of the Mississippi River during the 1890s, we follow the story of Magnolia Hawks, a young dreamer living aboard a showboat with her mother, a famous vaudeville singer. Life on the boat is a whirlwind of joy and drama, where the aspirations of artists traveling from town to town blend as they showcase their talents to the passengers. Magnolia falls madly in love with an attractive and charismatic mystic named Gaylord Ravenal, who shares her passion for show business but also harbors a wandering spirit that makes him unreliable.
The relationship between Magnolia and Gaylord flourishes amidst the lights and songs of the boat, but soon the differences in their aspirations and the clash of social classes begin to disturb the peace of their romance. The challenges intensify with the emergence of racial and economic issues in the community surrounding the show.
