The mudlark is "Wheeler" (Andrew Ray), an illiterate London street urchin of the mid-19th century. Having seen a picture of Queen Victoria on a coin, Ray determines to meet the Great Lady, and to that end he sneaks into Windsor Castle. Victoria (Irene Dunne) has sequestered herself in the castle since the death of her beloved Prince Albert, and has refused to make any public appearances, much to the consternation of Prime Minister Disraeli (Alec Guinness).
