Fred Astaire and Jane Powell star as a brother and sister dance team that is invited to England to perform at the same time as the royal wedding of Princess Elizabeth. On the cruise ship, Ellen (Powell) meets and falls in love with Lord John Brindale (Peter Lawford). Upon arriving in London, Tom (Astaire) finds himself in need of a new dance partner. His audition finds not only a new partner but a romantic interest in the form of Anne Ashmond (Sarah Churchill). Great dance numbers, including Astaire dancing on the walls and ceiling of his hotel room, and songs abound in this light romantic comedy.
