Song and dance man Jerry Travers is in London to open his show, produced by his good friend Horace Hardwick. He stays in Horace's suite the night before the show opens and becomes enamored with the woman in the suite below theirs, Dale Tremont. Due to a mix-up, Dale believes that Jerry is Horace. The only problem is that Horace is married to her old friend Madge and so Dale decides to teach him a lesson. After much singing and dancing, they eventually sort it all out.—garykmcd
