Two sets of lovers come together while working on a big musical.

At a twenty-sixth reunion of the Scandals Club, an organization comprised of women performers of the George White's Scandals show, comedienne Joan Mason announces her engagement to Scandals performer Jack Evans. As the women congratulate Joan, Jill Asbury, the daughter of former Scandals dancer Molly Hogan, approaches the group to introduce herself. Jill's mother left the show to marry Lord Asbury, an English nobleman, and for old time's sake, Joan invites the girl to attend the show's rehearsal. Joan's prospect for marriage dims when Jack introduces her to his spinster sister Clarabelle, who disapproves of Joan and reminds her brother of the promise that he made at his mother's death bed to postpone marrying until she achieved wedded bliss. At rehearsals the next day, Tom McGrath, the show's manager, mistakes Jill for one of the chorus girls. Smitten by Tom, Jill pretends to be Jill Martin, a struggling dancer, and asks Joan to keep her secret. When Joan warns Jill that Tom treats the chorus girls like sisters, she embarks upon a campaign to win his interest by appealing to his brotherly instincts. Meanwhile, Joan determines to marry off Clarabelle and arranges a date for her through an escort service. Jack has planned a surprise birthday party for his sister that night, and all of the show's performers gather at the Evans house to entertain. At the party, Billie Randall, one of the dancers, becomes jealous when Tom kisses Jill. Clarabelle is flattered by the attentions of her date, M. Montescu, until she discovers that Joan hired him through an escort service. After Clarabelle hurls an ax at her, Joan despairs of ever winning her approval and decides to call off the engagement. At rehearsals the next day, George White is so impressed by Jill's dancing that Tom suggests offering her the closing spot, which is coveted by Billie. When a jealous Billie learns Jill's real identity, she calls the British Embassy. Lord Quimby, a representative of the Embassy, is scandalized about Jill's appearance in the show and comes to the theater to persuade her to withdraw. When Tom learns that Jill has deceived him about her identity, he becomes enraged and Jill runs away. On opening night, Tom begins to search for her, and Jack tells Clarabelle that he plans to marry Joan over her objections. Clarabelle then goes to the theater to complain to Mr. White, and is knocked unconscious by a falling sandbag. Molly and her husband, Lord Asbury, go backstage before the show to tell Mr. White that they are thrilled about their daughter's appearance in the show, and he informs them about Jill's disappearance. During a mind reading act, Jack spots Jill in the audience, and when she sees her parents proudly sitting in their box seats, she goes backstage, reconciles with Tom and takes the stage in time to perform her ballet number. All ends happily when Clarabelle awakens after the performance and begins to sing Joan's praises.
