The film
One Rolls-Royce belongs to three vastly different owners, starting with Lord Charles, who buys the car for his wife as an anniversary present. The next owner is Paolo Maltese, a mafioso who purchases the car during a trip to Italy and leaves it with his girlfriend while he returns to Chicago. Finally, the car is owned by American widow Gerda, who joins the Yugoslavian resistance against the invading Nazis.
