They are persuaded to take the show to London, capitalizing on an imminent royal wedding. On the ship, Ellen meets and quickly fallls in love with the impoverished but well-connected Lord John Brindale. Whilst casting the show in London, Tom falls in love with a newly engaged dancer, Anne Ashmond. Tom assists Anne to reconcile her estranged parents and also asks his agent to locate Anne's supposed fiance in Chicago - only to discover that he's married. Carried away by the emotion of the wedding, the two couples decide that they will also be married that day.
