In the 1920s, English magician and illusionist Stanley Crawford, who on stage masquerades as Chinese conjuror Wei Ling Soo, travels to the French Riviera where he attempts to expose the secrets of spirit medium Sophie Baker. Sophie is suspected of exploiting the wealthy Catledge family and Stanley finds her staying in their home, having been invited there by Grace Catledge, who wants the clairvoyant's help in contacting her deceased husband. Though he is initially certain she is a fraud, the more time Stanley spends with Sophie, the more he begins to believe she might be genuine. Not, unsurprisingly, one of Allen's best.
