Air Marshall Hardie is a guest at a society dinner party in Hong Kong on the eve of his flight to Tokyo. During the course of the night, another guest is persuaded to share the details of a strange dream he had, which involved a plane crash in the mountains of Japan. Hardie takes little notice of the story until the following day, when he discovers the plane he had been intending to fly has been swapped for a Dakota, the very plane that featured in the mysterious dream. Stranger still, two last minute passengers arrive, taking the number of passengers up to match with that which the dream foretold. Hardie begins to wonder if it was indeed merely a dream — or a premonition which is about to become a deadly reality.
