Let's Dance is a musical comedy romance from 1950 featuring big name stars. Wealthy widow and single mother Kitty McNiel (Betty Hutton) is found after the war by her former USO partner Donald Elwood (Fred Astaire) and their friendship develops into something more. Kitty and Donald find that they work well together both onstage and off, but Kitty's in-laws are not at all happy with her relationship with Donald. Kitty's in-laws are determined to force her to live in a manner they consider appropriate to her status in society. If Kitty refuses and continues to see Donald, they intend to seek custody of Kitty's child. Even though Donald isn't rich, Kitty loves him and would do anything for them to stay together - except sacrifice her child. Kitty and Donald woo audiences with their song and dance routine but aren't as successful at wooing Kitty's in-laws. Will Kitty have to give up her lover to keep her child?
