Topsy is the main character in this movie. When the black girl who "jes' growed" is auctioned as a slave but nobody will bid on her, Little Eva purchases Topsy for a nickel. That's the one part of this movie that I found plausible: slaveholders often refused to buy children, since their upkeep in food usually exceeded any labour they performed. There's a gooey romantic subplot between Mariette (the niece of Simon Legree) and George Shelby, son of a prominent slaveholder. (imdb)

Casey and Babe are sisters who work in a department store and each year the store puts on a show. As expected, things are going wrong with every act until Casey comes out to help Babe with her song. They are a hit, but in the final act, Casey again comes out and this time the president sees her act and fires both her and Babe on the spot. Benny is able to book Casey, Babe and Dean into Vaudeville and their act is popular. (imdb)
