The story takes place on the eve of Easter in 1911. Don (Fred Astere Fred Astaire) and Nadine (Ann Miller Ann Miller) are not only emotional partners, but also partners on the stage, and their dance has conquered audiences one after another. However, feelings can change, and when Nadine's feelings for Tang are no longer, she also refuses to continue her business cooperation with Tang. So, Tang found the young, innocent and naive Hannah (Judy Garland Judy Garland) as his successor, and vowed to make her popular, in order to prove that Nadine is not important. Sure enough, under Tang's great praise, Hannah became famous, and her popularity attracted the attention of a colleague named Florence (Jules Mansin Jules Munshin). In fact, Tang is already deeply in love with Hannah, but he hides it very well.
