Danny Kaye (On the Double) stars as a neurotic American ventriloquist performing in Europe. In a parody of the 1946 thriller Dead of Night, Kaye is unable to control the words coming out of his dummy, resulting in a near-nervous breakdown. His manager andbest friend (David Burns) orders him to see a famous psychiatrist in Zurich. What follows is a zany adventure involving secret weapons, international spies and the beautiful Mai Zetterling (Only Two Can Play).
