When the temperamental star of a new Broadway musical revue in rehearsals walks out, director and choreographer Ted Sturgis (Gower Champion) suggests casting an unknown for the role. When it is announced in the newspapers, throngs of hopefuls show up. They sing about their hopes in the song, "Give a Girl a Break." The revue's musical composer, Leo Belney (Kurt Kasznar), champions ballerina Joanna Moss, while gofer Bob Dowdy (Bob Fosse) is enchanted by novice Suzy Doolittle (Debbie Reynolds). Then producer Felix Jordan (Larry Keating) persuades Ted's former dance partner, Madelyn Corlane (Marge Champion), to come out of retirement to try out, much to Ted's great discomfort. Leo, Bob, and Ted sing about the challenges of re-writing the show for a new performer in "Nothing is Impossible."
