When a Broadway leading lady breaks her ankle, it's up to fresh-faced newcomer Peggy Sawyer (Ruby Keeler) to step in and save the show. Meanwhile, because of the accident, the production's ailing director (Warner Baxter) must grapple with losing the show's financial backer. This quintessential Busby Berkeley musical features some of cinema's most treasured tunes, including the title song, "Lullaby of Broadway" and "Shuffle Off to Buffalo."
