A young woman named Elizabeth, and her husband Robert, move temporarily into the small English coastal town of Cleveham. It is not long before the local people learn that Elizabeth seems to possess a gift of extrasensory perception. Edward Fearns is skeptical, and finds it all amusing. However, when he witnesses evidence that not only could Elizabeth be a fake, but she may also be a con artist, he sets about trying to unravel the mystery. As he gets closer to the truth, he starts to realise just how strange the events are.
