Chinese conjuror Wei Ling Soo (Colin Firth) goes on a mission to the Côte d'Azur to debunk the alluring young clairvoyant Sophie Baker. To his great surprise and discomfort, however, Sophie accomplishes numerous feats of mind-reading and other supernatural deeds that defy all rational explanation, leaving him dumbfounded. What follows is a series of events that are magical in every sense of the word and send the characters reeling. In the end, the biggest trick this film plays is the one that fools us all.
