Bing plays Virgil Smith, an American phonograph salesman whose fox terrier companion takes a fancy to the persnickety poodle of countess Johanna Augusta (Joan Fontaine).
Music, merriment, and romance blend blissfully while Bing sings "Friendly Mountains" and "I Kiss Your Hand, Madam," and Strauss melodies fill the air. Co-starring Sir Cedric Hardwicke and William Bendix, the classic fantasy also features a marvelous score by Jimmy Van Heusen and Johnny Burke, along with such hits as "Busy Doing Nothing" and "Once and for Always. But thanks to some American know-how, the crooner is quickly hailed as a wiz of a wizard and granted the right to teach Rhonda Fleming, the King's fetching niece, some decidedly contemporary romantic tricks. Der Bingle is a turn-of-the-century blacksmith who is knocked unconscious only to awaken in sixth-century Camelot.
